Question

Hello, I have a assignment where the user inputs a word and the out will then tell the user how many of the five vowels are in the word so for example if I typed the word hello, it would output {0 1 0 0 0 } since there is only one vowel and that is e which is in the second row, I have most of it done, but I can't seem to figure out how to get the final part to work basically I need to make it so it will keep asking the user to Enter a string until I type STOP. I need it so it keeps asking to enter a string.

Tldr; I basically need my program to keep asking the user to enter a string, and to keep doing that until stop is typed in all upper case.

public static void main(String args[]){

Scanner keyboard= new Scanner(System.in);
System.out.println("Enter string ");
String input;
input = keyboard.next();
String test = input;
int[] vowels = vowelCount(input);
  
while (!"STOP".equals(input)){
input = keyboard.next();

System.out.print("{");
for(int i=0; i<5; i ++) {
System.out.print(vowels[i] + " ");

}
System.out.print("}");
}   
}

static int[] vowelCount(String str) {
int vowels [] = new int[5];
str = str.toLowerCase();
for (int i = 0; i < str.length(); i++) {
if ((str.charAt(i) == 'a'))
vowels[0]++;
if ((str.charAt(i) == 'e'))
vowels[1]++;
if ((str.charAt(i) == 'i'))
vowels[2]++;
if ((str.charAt(i) == 'o'))
vowels[3]++;
if ((str.charAt(i) == 'u'))
vowels[4]++;
}
return vowels;
}
}

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Here a new java program with name "Main.java" is created, which contains following code.

Main.java :

import java.util.*;//import package
public class Main//Class
{ //main method
public static void main(String args[]){
//creating object of Scanner class
Scanner keyboard= new Scanner(System.in);
System.out.println("Enter string ");//asking user to enter string
String input= keyboard.next();//reading string
//using while loop to check whether STOP is the string
while (!"STOP".equals(input)){
int[] vowels = vowelCount(input);//calling function to check number of vowels
System.out.print("{");//used to print {
for(int i=0; i<5; i ++) { //for loop will goes till 5
System.out.print(vowels[i] + " ");//print vowels count
}
System.out.print("}");//print }
System.out.println();//used for blank line
System.out.println("Enter string ");//again asking user to enter string
input = keyboard.next();//reading string
}   
}
//method to count number of vowels
static int[] vowelCount(String str) {
int vowels [] = new int[5];//creating array to store vowels count
str = str.toLowerCase();//converting string to LowerCase
//using for loop that will goes till length of string
for (int i = 0; i < str.length(); i++) {
if ((str.charAt(i) == 'a'))//checking for a
vowels[0]++;//increment a's count
if ((str.charAt(i) == 'e'))//checking for e
vowels[1]++;//increment e's count
if ((str.charAt(i) == 'i'))//checking for i
vowels[2]++;//increment i's count
if ((str.charAt(i) == 'o'))//checking for o
vowels[3]++;//increment o's count
if ((str.charAt(i) == 'u'))//checking for u
vowels[4]++;//increment u's count
}
return vowels;//return array of vowels
}
}

======================================================

Output : Compile and Run above program to get the screen as shown below

Screen 1 :Main.java

Enter string HEEOO 10 2 0 2 0 Enter string Pink 10 0 1 0 0 Enter string STOP . .Program finished with exit code 0 Press ENTER to exit console
