 Java program to accept  word and check if it is palindrome

import java.util.Scanner;

// converting to uppercase as palindrome is case insensitive

String str = sc.next().toUpperCase();

sc.close();

String temp = reverse(str);

System.out.print("Palindrome");

else

System.out.print("not");

}

String temp ="";

for(int i=str.length()-1;i>=0;--i) {
