Passing parameters in Arrays

[mwn1218]

Hey, I'm a newbie to java and am getting a syntax error on my passing of the array in the main method. It does not like that I am passing Num3, Num4. Since its an array do I have to pass it a certain way? Any insight would be helpful, Thanks in advance!


Here is the coding I have in the method:

public static int intArray(int [][] myArray){
int[][] intArray = new int[2][10];
for (int r = 0; r<myArray.length; r++){
for (int c = 0; c<myArray[r].length; c++){
myArray[r][c] = r++;
}//close 2nd for
}//close 1st for
}//close myArray method

Here is the coding I have in the main:

else if (commandtoken.equalsIgnoreCase("NUM")){
int Num3 = Integer.parseInt(st.nextToken());
int Num4 = Integer.parseInt(st.nextToken());
int[][] myArray = new int[Num3][Num4];
System.out.println("Number Array with " + Num3 + " rows and " + Num4 + " columns " + intArray(Num3, Num4));

This is the error I am receiving:

Assign1.java [49:1] intArray(int[][]) in Assign1 cannot be applied to (int,int)

Num4 + " columns " + intArray(Num3, Num4));
^
1 error
Errors compiling main.

System.out.println ("Number Array with " + Num3 + " rows and " + Num4 + " columns " + intArray (myArray));

note:

public static int intArray(int [][] myArray){
       int[][] intArray = new int[2][10];

the second line defines a new two-dim array, which is never used. Delete it.

You want to do :-

System.out.println("Number Array with " + Num3 + " rows and " + Num4 + " columns " + intArray(myArray));

ie. actually pass the array as the parameter to your method.

Maybe this has nothing to do with this, but that r++ statement will make the r index overflow.

Your right there. He probably meant to do myArray[r][c] = r + 1;
