Java program to print the last character of every word in a given string

Problem Statement

Write a Java program to print the last character of every word in a given string
Conditions

Ignore all the digits and whitespaces
Input

Hey3 Java Learners

Output

as

Explanation

As the first word Hey3 has digit in its last position, ignore it. The second word Java has multiple white spaces after it. But those white spaces should be ignored and only the last character should be printed. Likewise, the last character of the word Learners should be printed. Thus, the output as.

code:

import java.util.Scanner;
class Solution{
    public static void main(String[] args){
        Scanner s=new Scanner(System.in);
        String input=s.nextLine();
        s.close();
        char[] result = input.toCharArray();
        for(int i=0;i<result.length;i++){
            if(Character.isWhitespace(result[i]) && !Character.isDigit(result[i-1]) && !Character.isWhitespace(result[i-1])){
                System.out.print(result[i-1]);
            }
            else if(i == result.length-1 && !Character.isDigit(result[i])){
                System.out.print(result[i]);
            }
        }
    }
}
