public class Palindrome
{
public void main(String s)
{
String rev="";
char ch =' ';
for(int i =0;* look at comments below. ch= s.charAt(i ); rev=ch+rev;
}
if(s.equalsIgnoreCase(rev)
System. out.print( s+ " is a Palindrome String");
else
System. out.println( s+ "is not a Palindrome String");
}
}

Tarun304: The line marked with * will be for(int i=0; i<s.length (); i++)

Tarun304: Then write {

Tarun304: Continue the from the above
