Q18: Java Program to find weather a given string is palindrome or not

import javax.swing.*;

class palindrome{
	public static void main(String args[]){
		String wd;
		int i, len;
		boolean ispal;

		wd = JOptionPane.showInputDialog("Enter a Word:");
		len = wd.length();
		
		i=0;
		ispal=true;
		for(;i<=len;){
			if(wd.charAt(i) == wd.charAt(len-1)){
				i++;
				len--;
				}
			else{
				ispal = false;
				break;
			}
		}
		if(ispal==true)
			System.out.println("The String " + wd + " is Palindrome.");
		else
			System.out.println("The String " + wd + " is not Palindrome.");
	}
}
