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]

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:

(Toggle Plain Text)

    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:

(Toggle Plain Text)

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?
