Java program for palindrome - For String

Write a program to find Whether given string is palindrome or not.

import java.util.Scanner;

public class Stringpolindrome {
    public static void main(String[] args) {
  
        int i,j=0;
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter your String:-");
        String str=sc.next();
        char c[]=new char[20];
        c=str.toCharArray();
        i=str.length();
        --i;

    while(j<=i)
    {
        if(c[i]!=c[j])
        {
            System.out.println("The given string "+ str +" is not polindrome");
            System.exit(0); 
        }
        ++j;
        --i;
      
    }
    System.out.println("The given string" + str +"is polindrome");
    }
}
Output 1:
