import org.testng.annotations.Test;

public class SampleProgram6 {

@Test
public void testMySkills() {
   String str = "Hello";
   if(checkPolindrome(str)){
    System.out.println(str+" is a polindrome");
   }
   else{
    System.out.println(str+" is not a polindrome");
   }
   
}

public Boolean checkPolindrome(String str) {
    int start = 0;
    int len = str.length();
    int end = len-1;
    while(start<=end) {
        if(str.charAt(start) != str.charAt(end)){
           return false;
        }
        start++;
    }
    return true;
}
