palindrome is nothing but while revering the word we get the same word as result.
example:
wow=wow
level=level
mom=mom
dad=dad
malayalam=malayalam
program:
class Palindrome{
public static void main(String[] args) {
String s="sobhi";
String rs="";
int len=s.length()-1;
while(len>=0){
rs=rs+s.charAt(len);
len=len-1;
}
if(s.equals(rs)){
System.out.println("palindrome");
}
else{
System.out.println("not a palindrome");
}
}
output:
sobhika@sobhika-HP-Laptop-15-db1xxx:~$ javac Palindrome.java
sobhika@sobhika-HP-Laptop-15-db1xxx:~$ java Palindrome
not a palindrome
