Write a Java program to display all the vowels from a given string

Here's a simple Java program that takes a string as input and displays all the vowels present in that string:

Program : ( Write a java program to display all the vowels from a given string)

import java.util.Scanner;

public class DisplayVowels {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        // Input string from the user

        System.out.print("Enter a string: ");

        String inputString = scanner.nextLine();

        // Displaying vowels in the input string

        System.out.print("Vowels in the given string: ");

        displayVowels(inputString);

        scanner.close();

    }

    private static void displayVowels(String input) {

        // Convert the input string to lowercase to simplify vowel checking

        input = input.toLowerCase();

        for (int i = 0; i < input.length(); i++) {

            char ch = input.charAt(i);

            // Check if the character is a vowel

            if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u') {

                System.out.print(ch + " ");

            }

        }

    }

}

Note : This program prompts the user to enter a string, converts it to lowercase to simplify vowel checking, and then iterates through each character to display the vowels. You can copy and paste this code into a Java file (e.g., DisplayVowels.java) and then compile and run it using a Java compiler.

Output :
