String is a palindrome or not

Write a Java program that checks whether a given string is a palindrome or not. Ex MADAM is a palindrome.

Program Code in JAVA:

import java.io.*;

class Palindrome

{

public static void main(String[] args) throws Exception

{

String str1, str2;

DataInputStream dis=new DataInputStream(System.in);

System.out.println("Enter a String");

str1=dis.readLine();

StringBuffer tmp=new StringBuffer(str1);

tmp.reverse();

str2=new String(tmp);

System.out.println("The String after Reverse is "+str2);

if(str1.equals(str2))

System.out.println("The given String "+str1+" is palindrome");

else

System.out.println("The given String "+str1+" is not palindrome");

}

}

Program Output:

c:\java>javac Palindrome.java

c:\java>java Palindrome

Enter a String

madam

The String after Reverse is madam

The given String madam is palindrome
