Q4) Write a program in Java to input a word and check if it is palindrome word or not using a function. The function should return 1 if the word is palindrome else return 0.
A word is called palindrome if its reverse form is equal the original word.
Example: madam Reverse Form: madam
Program
import java.util.Scanner;
public class Q4
{
public static int palindrome(String str)
{
String rev="";
int i;
for(i=str.length()-1; i>=0; i--)
{
rev=rev+str.charAt(i);
}
if(str.compareToIgnoreCase(rev)==0)
{
return 1;
}
return 0;
}
public static void main(String args[])
{
String s;
Scanner sc=new Scanner(System.in);
System.out.print("Enter a String: ");
s=sc.nextLine();
if(palindrome(s)==1)
{
System.out.print("Palindrome Word");
}
else
{
System.out.print("Not Palindrome Word");
}
}
}Output
