Conversion of 'Array object'!

[Nirmala]

Hi all,

public void printArray(long a[])
{
for(int i=0;i<a.length;i++)>
{
System.out.println(a[i]);
}
}
If this method is called like this
int b[]={1,2,3,4};
printArray(b);
it says no method matching 'printArray[int)' found error I am getting.
Is it because of Once array is constructed,it can not be modified(immutable)!.
I am not clear,please can some body help me.
Thanks in advance.

Primitive arrays are not automatically "widened" like object reference arrays.

Nirmala,
When you make call printArray() with integer argument, It will look for printArray(int[]) which is not defined. Look at the following code :
You make call using long[] or You overload printArray method for int[] argument.

import java.awt.*;
class Gd {
public void printArray(long a[]) {
for(int i=0;i < a.length;i++)
System.out.println(a[i]);
}
public static void main(String args[]){
long b[]={1,2,3,4};
Gd x = new Gd();
x.printArray(b); //passing long argument
}
}
