    Java Code:
    import javax.swing.*;
    public class copyarraydemo{
      public static void main(String[] args){
       String[] copyFrom =new String[5] ;
       String[] copyTo =new String[5];
       String a="";
       int n,num=0;
       int index=0;
       		for( n=0; n<4; n++){
    			copyFrom[n] = JOptionPane.showInputDialog("Enter A String:");
    			 a= a + copyFrom[n] + "\n";
       	 JOptionPane.showMessageDialog(null,"Strings: \n"+ a);
       	  while(num>4 || num<1){
       	  num=Integer.parseInt(JOptionPane.showInputDialog("Enter Index:"));

    You mean print the value of num?

    @op, please use code tags next time when your are posting again in the forum. Unformated codes are really hard to read. If you don't know how to do that, check on my forum signature.
