9 Amazing Examples of Parsing XML in Android w. Tuts [Source Code] [Video]

Ive found the best way of learning something in Android is to look at about 5 to 10 different varriations of code that accomplish the same thing. Doing this gives you a sense of  whats consistant in all the examples and how you can and can and cant manipulate the code.

9.IBM Android Tuts: 
If your new to Android this example and explaination might be a little confusing, its loaded with complicated java jargon experienced developers love to throw around casually as if they were born with such a vocabulary and you should of to, but in reality the reason why programming is complicated isnt because it actually is complicated, its because the people who useually become programmers are complicated. Its there way of scaring away the avg person from ever trying to learn their god like skills.

WALKTHROUGH:TNB Java Tut 42 -"toString" [VIDEO] [SOURCE CODE]

This is a full walk-through of Java Tutorial 42 by TheNewBoston. Each walk-through includes:

• Embedded Video Tutorial
• Text Transcript of the tutorial broken down into steps.
• Source code
• Visual Breakdown of the code

In this walk-through you will learn about using the "toString" method, a very useful method used to give any object a default string representation.

Step 1.Create a class and name it "stringDinger"

 public class stringDinger {  
 }  

inside of the "stringDinger" class:

Step 2.Create 3 int vars(month, day, year)

  private int month;  
  private int day;  
  private int year;  

Step 3.Create a constructor for the "stringDinger" class that accepts 3 parameters.

 public stringDinger(int m,int d,int y){  

inside of the stringDinger constructor:

Step 4.Set each of the incoming parameters to their corresponding variables:

  month=m;  
   day=d;  
   year=y;  

Step 5.create a print function statement that prints the sentence "the constructor for this is %s\n , this"(note: "using "this" in this case will equal whatever you're "toString" method returns )

  System.out.printf("the constructor for this is %s\n",this);  

end of stringDinger constructor.

Step 6.Create a "toString" method that returns the variables formated like this : "month/day/year":

  public String toString(){  
   return String.format("%d/%d/%d",month,day,year);  
  }  

end of "stringDinger" class

Step 7.Create a new class with a main method, name the class "useTheDinger"

 class useTheDinger{  
  public static void main(String[] args){  
 }  
 }  

inside the  main method of the "useTheDinger" class:

Step 8.Create a stringDinger object with the parameters 4,5,2011

  stringDinger theDingerSpeaks = new stringDinger(4,5,6);  

End of Tutorial

   month=m;  
   day=d;  
   year=y;  
   System.out.printf("the constructor for this is %s\n",this);  
 }  
  public String toString(){  
   return String.format("%d/%d/%d",month,day,year);  
  }  
 }  

"useTheDinger" Class

 class useTheDinger{  
  public static void main(String[] args){  
   stringDinger theDingerSpeaks = new stringDinger(4,5,6);  
   System.out.println(theDingerSpeaks.toString());

CHALLENGE:Java Tut 36-37-Display Reg Time

The following is a challenge for new developers that have completed:

 Java Tutorial - 36-37 Displaying Regular Time by theNewBoston
 To get the most out of these challenges try them a few hours or the day after watching/following along with the actual video.

 

CHALLENGE!!

(Before starting any of the challenges always declare a class and a main method unless told otherwise)

 Difficulty:★★
 

1.Create a class and name it "Time".Unlike classes we've created in the past you dont need to declare a main method.

2.Create 3 int vars. name them hour, minute, second.

3.Create a method,name it setTime, it should accept 3 parameters(int h, int m , int s)

Inside the setTime method:

• if h is greater than 0 and less than 24 then set h to hour, else set the hour to 0 by default.This should be accomplished in one line of code( Hint:use the "ternary operator" instead of a if statement)

• if m is greater than 0 and less than 60 then set m to minute, else set the minute to 0 by default.(Hint: "ternary operator")

• if s is greater than 0 and less than 60 then set s to second, else set the second to 0 by default.(Hint: "ternary operator")

End "setTime" method 

4.Create another method.Name it toMilitary.

Inside the to Military method:

• Create a return statement that will format the "hour" , "minute" and "second" vars to display in military format.
  
  Example of console output:18:30:00
  End "toMilitary" method

5.Create a method,name it toRegTime

Inside the "toRegTime" method:

• Create a return statement that will format the "hour" , "minute" and "second" vars to display in standard time format. (hint:Ull need to use the Modulus (%) operator
  
  Example of console output:6:30:00 PM

End "toRegTime" method

End of "Time" class

6.Create another class and name it testTime .Create a main method.

Inside the main method of testTime class:

• Declare a new Time object and name it tickTock.

• Print tickTock.toMilitary

• Print tickTock.toRegTime

• Call the setTime method with the parameters (13,27,6)

• Print tickTock.toMilitary

• Print tickTock.toRegTime

End of "testTime" class

B.A.M.F Challenge:

B.A.M.F Challenges & why you want to always at leas try them explained Here:http://bit.ly/ogivqe

Difficulty: ★★1/2

 Create a java console program with a method that accepts a multidimensional array in its parameters.When the method is called it should print the array out to the console as a table.If you've done everything right you're results should look like this:

This is the the Multi Array

8        9        5          12
55      12        32         22
15       4        39         83

CHALLENGE!!

(Before starting any of the challenges always declare a class and a main method unless told otherwise)

 Difficulty:★2/3

1.Create a multidimensional array. It should have at least 3 arrays inside of it and each array should have several values.

2.Create a method that accepts a multidimensional array in its parameters, name the array in the parameters "x" and name the method "display"[

3.Inside the display method create a for loop, name you're counter "row; loop  through until x.length is less than "row" ; increment by 1

Inside of the "row" for loop insert: [

Another for loop. name you're counter "column"; loop  through until x.length is less than "x[row].length;increment by 1. Inside the "column" for loop insert:

   1.A print line statement that prints  x[row][column] + "\t"]

Print line statement that prints: a blank line] ]

4.In the main method write a print line statement that reads "This is the array table"

5.In the main method call the display method and place you're array in the parameters

Note: I am trying to experiment to find the best way to explain loops in words. Everything that is Orange is inside of the "Row" for loop and everything that is red is inside the "column" for loop.

Introducing B.A.M.F Challenges

 (B.A.M.F's Make Money Like George Jung From Blow and you will to once you master the art of I2J Translation)

B.A.M.F Challenges are for those of you feeling a little cocky, Instead of giving you step by step directions I will only give you a abstract goal of the challenge and its up to you to figure out how to make it happen.Even if you cant always complete the B.A.M.F challenge, you should always at least try and then move down to the reg challenge if youre struggling.B.A.M.F Challenges help youre brain become what I call a Java "translator" , as in you can listen to a client explain something they want done in simple English and convert it in you're mind to rough Java.Almost every new programmer gets to a point where they can read source code and understand what its doing, but struggle with creating a program from a idea alone without help or alot of research.The end results should still be the same as the regular challenge.

CHALLENGE: Intermediate Java Tut's 4&5

The following is a challenge for new developers that have completed:

Intermediate Java Tutorial - 4&5 -Collections & arrayLists by theNewBoston

 

Legendary Challenge: 

Difficulty:★ ★ 1/2

Create two arrayLists, the first array must have 5 unique strings and the second array must consist of only the last 2 strings from the first array.Then create a method that will iterate through the first arrayList and filter out any strings that are also in the second array. Print your results.

Legendary Challenges consist of only a very broad description of the challenge making them a little harder.The end results should still be the same as the regular challenge.

CHALLENGE 

 Difficulty:★

1. Create a String array named "things" containing the strings "eggs", "lasers","hats" and "pie"

2. Create a new ArrayList named "list1"
3. Create a For loop that adds the items from the array "things" to "list1"

4. Create a String array named "things2" containing only the strings "lasers" & "hats" 

5. Create a new ArrayList named "list2"

6. Create a For loop that adds the items from the array "things2" to "list2"

7.Print all the strings in list1 one using a for loop

End of Tut 4/Start of Tut 5

8.Create a method a called editList that uses two collection parameters and names them "A1" and "A2"
(to make it less confusing just remember that in a later step we will call the editList method and use "list1" & "list2" as parameters) 

9. Inside the editList method loop through each string in "A1" and make sure none of the strings are the same as any of the strings in "A2" 

10.If any of the strings from "A1" do match any of the strings from "A2" delete the string from "A1"

11.Call the editList method using "list1" & "list2" as parameters

12.Print a blank line

13.Print each of the strings in list1 using a for loop 

Note: Please keep in mind this blog is a work in progress and ive learned quickly that teaching is alot harder than just following along .
