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!!

 Create a enhanced for loop that sums the contents of a array.

CHALLENGE!!

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

 Difficulty:★

1.Create a int array with 8 values.
2.Create a int var , name it total and set it to 0
3.Create a enhanced for loop , set it to you're array. Each time it loops it should:
            *Add a value from the array to the total var
4.Print the total var to the console

Difficulty: ★★ 1/2

 Create a java console program using arrays and for loops that simulates a 6 sided die being tossed 1000 times. Then print the amount of times it fell on each side of the die to the console. Your console output should look something like this: 

Face      Frequency

1                182          

2                 220         

3                134          

4                278          

5                169         

6                188          

CHALLENGE!!

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

 Difficulty:★1/2

1.Create a Random variable and name it rand
2.Create a int array that holds 7 int's, name it freq. 
3.Create a for loop that loops 1000 times.Each time it loops it should:

       *++freq[1+rand.nextInt(6)];

4.Below the for loop print a header that reads "Face        Frequency"
5.Create another for loop:
  Start you're "counter" at 1, the loop should continue as long as face is less than the length of the freq array , increment by 1 , each time it loops it should :
                   *Print the index , a few spaces and the value of the index position.(See the example in the                      B.A.M.F example if you're confused.
