How to check whether a string is palindrome
Palindorme in java source code : Palindrome are strings, that remains unchanged even when reversed for example "mom","malayalam",etc
import java.util.Scanner;

public class Palindrome {
/**

*/
public static void main(String[] virat) {
// TODO Auto-generated method stub
Palindrome palindromeNumber = new Palindrome();
palindromeNumber.checkPalindrome();
}
private void checkPaliandrome() {
// TODO Auto-generated method stub
String str = null;
System.out.println(" Please enter the string that you want to check is that a paliandrome");
Scanner scanner = new Scanner(System.in);
str = scanner.next();
//str= "worldcupcricketekcircpucdlrow"; //test value
//System.out.println(str);
int len = str.length();
System.out.println(len);
int first =0;
int last =len-1;
int flag = 0;
int loopLen = len/2;
//System.out.println(str.charAt(first));
//System.out.println(str.charAt(last));
for(int count=0;count<loopLen;count++){
if(str.charAt(first)!=str.charAt(last)){
flag =1;
break;
}
//System.out.println(str.charAt(first)+"--"+str.charAt(last));
first=first+1;
last=last-1;
}
String output = flag ==0? " paliandrome" : "not a paliandrome";
System.out.println(str+ " is "+output);
}
