passing variables from one method to another?

public class something

{

        public void methodOne()

        {

                int i = 0;

                int x = 4;

                String word = "hello";

                

                int[] abc = new int[26];

        while( i < 26) 

        {

            abc[i] = x;

            x++;

            i++;

        }

        

        methodTwo(i, x, word, abc);

        }





        public void methodTwo(i, x, word, abc)

        {

                int a = i;

                int b = x;

                String c = word;

                int d = abc;

        }





}

I tried that, but it didn't work, I got an <identifier>expected and ')' expected error...

methodTwo doesn't have any variable types declared.
[PHP]
//this works
public class something
{
public void methodOne()
{
int i = 0;
int x = 4;
String word = "hello";

int[] abc = new int[26];
while( i < 26)
{
abc[i] = x;
x++;
i++;
}

methodTwo(i, x, word, abc);
}
public void methodTwo( int i, int x, String word, int abc[])
{
int a = i;
int b = x;
String c = word;
int d[] = abc;
}
}
[/PHP]
btw, please work at the issue before posting, these are common program errors and it shows us that you do not know what you are doing. I advise you to read up so references.

yeah, thanks, I noticed.

I have been a little jumpy recently...

well I just have hit another stumbling block, I can't invoke a method that has a passed array within its argument.

like if I have:

    public void initAbc(){

        String[] abc = new String[7];

        //destinations within array

        abc[0] = "[1]   fasd";

        abc[1] = "[2]   fdas";

        abc[2] = "[3]   dfafsd";

        abc[3] = "[4]   Hedfrmes";

        abc[4] = "[5]   dfas";

        abc[5] = "[6]   dfas";

        abc[6] = "[7]   asdfasfds";

        

        printDestinations( abc );

    }

    

    public void printAbc( String abc[] )

    {

        int i = 0;

        while ( i < 7 )

        {

            System.out.println(abc[i]);

            i++;

        }

    }

if I try to invoke it in another class, for instance:



classSomething abc = new classSomething();



abc.initAbc();



abc.printAbc(); <-- doesn't work.

First of all, it doesn't work because printAbc() contains arguments and to me it looks like it doesnt have any arguments! And doesn't initAbc() call printtAbc automatically?
