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

Inside the "average" method:

2.Declare a int variable, name it total and set it to 0.

3.Create a enhanced for loop that loops through the "numbers" parameter being passed in.

Inside the enhanced for loop:
4.set total+=x;

5.return total divided by the amount of numbers you passed in(hint: numbers.length)

Back in the main method:

6.Create a print line statement that calls the "average" method and place 8 values in its parameters.

CHALLENGE:Java Tut 32-34-Arrays in Methods & Multidimensional Arrays

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

 Java Tutorial's 32-34 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.

 

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. If this made it easier for you to understand or you have some suggestions to improve these challenges leave it in a comment below!!

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 . If something is explained poorly or you have a suggestion to reword a step please leave a comment below so we can make this the best resource possible for up and coming developers.

Dr.Java -Simple IDE for Learning Java

A lot of people these days are getting into development just to develop Android apps, which. Is great because more developers means more great learning resources poping up but, before you can code with the best of them your going to have to learn java. Eventually your probably going to end up using Eclipse (the recommended IDE for android) but, learning the ins and outs of eclipse is a task by itself. Trying to jum right into Eclipse while trying to learn java at the same time would be like having no musical background and tying to dj with the top of the line equipment. Dr.Java is a stripped down ide with just the essentials so you can focus your time on the java syntax.Best of all,its lightweight and.....ITS FREE!!!
