I don't know if that is allowed now in the latest jdk release...
My friend sent a request about that feature a few months ago.

As far as i know, you cannot just do that. You have to loop over their elements and do the casting.

here is an example,

Code:

public class test{
	public static void main(String args[]){
		Object[] t = {"I","am","who","am"};
		String[] s = new String[t.length];
		int x=0;
		for(Object temp:t){
			s[x] = (String)temp;x++;
		}
		for(String temp:s){
			System.out.println(temp);
		}
	}
}

HI sukatoa,
I tried in ur way but following error occured

The java class could not be loaded. java.lang.UnsupportedClassVersionError: (Unsupported major.minor version 49.0)

Here is another example, using List

Code:

import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collection;

public class test{

	static ArrayList<Object> a = new ArrayList<Object>();
	static ArrayList<String> al;

	public static void main(String args[]){

		Object[] t = {"I","am","a","Java","Programmer"};
		a.addAll((Collection)Arrays.asList(t));
		al = new ArrayList<String>((Collection)a);	

		for(String castedInternally:al)
			System.out.println(castedInternally);
	}
}

What jdk version did you use?

[John_28]

Am using jdk1.6.0_04.

Im using update 3....

There should be a problem at your side....
those are compilable and runnable code....

But, my example has a different approach,
all objects inside the Array of object is a String representation.

How about that {abc,xyz}?

Are abc and xyz are Strings too? or has a String representation?
