Array

[fraternity lawson]

hello,
Why does the following code is showing an error

public class sum
{
public static void main(String[]args)
{

byte[] array1,array2[];
array2=array1;
}
}

Hi fraternity,
<code>byte[] array1, array2[]</code> produces <code>array1[], array2[][]</code>. These are not equivalent. <code>array1</code> has one dimension, <code>array2</code> has two dimensions.
You can only assign arrays of the same 'type'. Arrays have a class type that is determined when they are created. See JLS §10.8
Try the following:

public class sum
{
    public static void main(String[]args)
    {
        byte[] array1,array2[];
        // create the arrays
        array1 = new byte[3];
        array2 = new byte[4][3];
        
        System.out.println(array1.getClass());
        System.out.println(array2.getClass());        
    }
}

Hope that helps.

lawson,
if you want to declare array2 as one dimensional array then
byte[] array1,array2;
for assigning the array1 to array2
you should construct array1
array1=new byte[5];
array2=array1
