Answer to Question #296294 in Java | JSP | JSF for Mener

Question

Write a program to take a String as input then display the palindrome word in one column and its position in another column.

Example:

Enter a String

My Mom brought a racecar

Mom \t 2

racecar \t 5

for(i=0;i<l;i++) {

c = s.charAt(i);

if(c != ' ') {

w=w+c;

r=r+c;

} else {

if(w.compareToIgnoreCase(r)==0)

w=""; r=""; //Use this code to search palindrome words

Answer 1

import java.util.*;


class App {


	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		System.out.println("Enter a String: ");
		String s = in.nextLine();
		int l = s.length();
		String w = "";
		String r = "";
		int position = 0;
		for (int i = 0; i < l; i++) {
			char c = s.charAt(i);
			if (c != ' ') {
				w = w + c;
			} else {
				position++;
				for (int j = w.length() - 1; j >= 0; j--) {
					c = w.charAt(j);
					r = r + c;
				}
				if (w.compareToIgnoreCase(r) == 0 && r.length() > 1) {
					System.out.println(w + "\t" + position);
				}
				w = "";
				r = "";
			}
			if (i == l - 1) {
				position++;
				for (int j = w.length() - 1; j >= 0; j--) {
					c = w.charAt(j);
					r = r + c;
				}
				if (w.compareToIgnoreCase(r) == 0 && r.length() > 1) {
					System.out.println(w + "\t" + position);
				}
			}
		}


		in.close();
	}
