Question

Write a JAVA program that has a method which accepts a string and prints it back to the user with all vowels replaced with *'s (multiple asterisks not '*s') with a new line after the string. The method signature should look like this:

public static void replacePrint(String input)

Answer 1

public static void replacePrint(String input) {
    for (int i = 0; i < input.length(); i++) {  // go through all characters
        char ch = input.charAt(i);
        if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ||
                ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') {
            System.out.print("*");
        } else {
            System.out.print(ch);
        }
    }
    System.out.println();
}

public class VowelsReplace {

    public static void replacePrint(String input) {
        for (int i = 0; i < input.length(); i++) {  // go through all characters
            char ch = input.charAt(i);
            if (ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' ||
                    ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U') {
                System.out.print("*");
            } else {
                System.out.print(ch);
            }
        }
        System.out.println();
    }

    public static void main(String[] args) {
        replacePrint("Hello How are you?");
    }
}
