How do you remove vowels from a word and type it?

Question

I try to write a program that asks someone to enter a word, and then the program removes any vowels in the word and prints the remaining consonant. This is what I have so far:

package r7;

import java.util.Scanner;

public class Disemvowel {
    public static void main(String[] args) {
        Scanner stdin = new Scanner(System.in);
        System.out.println("Please enter a word");
        String word = stdin.next();
        String disemvowlmentWord = "";
        int len = word.length();

        for (int i=0; i<len; i++) {
            char c = word.charAt(i);
            if (c != 'a' | c != 'e' | c != 'i' | c != 'o' | c != 'u')
                disemvowlmentWord = disemvowlmentWord + c;
        }
        System.out.println(disemvowlmentWord);
    }
}

When I run it, it simply retypes any word I enter.

Answer 1

You used bitwise or (but each vowel is not some other vowel), I think you wanted a logical and. it

if (c != 'a' | c != 'e' | c != 'i' | c != 'o' | c != 'u')

should be something like

if (c != 'a' && c != 'e' && c != 'i' && c != 'o' && c != 'u')

You can also use a loop for-each, and I would prefer StringBuilderfor creating a few immutable String(s). Sort of,

StringBuilder sb = new StringBuilder();
for (char c : word.toCharArray()) {
    if (c != 'a' && c != 'e' && c != 'i' && c != 'o' && c != 'u') {
        sb.append(c);
    }
}
System.out.println(sb);

, (- ),

if (!(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u'))

, String. - ,

System.out.println(word.replaceAll("[a|e|i|o|u]", ""));
