How to find out the percentage of vowels in a string?
package scanner;
import java.util.Scanner;
public class GuessSentence {
public static void main(String args) {
Scanner sc = new Scanner(System.in);
System.out.println("Type a sentence");
String sentence = sc.nextLine();
System.out.println("You entered the sentence " + sentence);
System.out.println("The number of words in the sentence is " + sentence.length());
char chars=sentence.toCharArray();
int count = 0;
for (char c : chars) {
switch(c) {
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
count++;
break;
}
}
System.out.println("The numner of vowels in your sentence is " + count);
System.out.println("The percentage of vowels is " + 100 * count /sentence.length() + "%" );
}
}
Thank you to everyone who helped, I was able to get the correct outcome which i was looking for so i appreciate all the help recieved.

You want (100.0 * count / sentence.length()). You're using the % operator which is the modulo of two numbers

When you calculate the percent you do:

But % is the modulo operator, which calculates remainder. You wanted to divide:
sentence.length() / count
However this will still not get you the right results as the scale is not right, and you are dividing incorrectly. It should be:
100 *count / sentence.length()
Or
100.0 *count / sentence.length()
If you want to avoid truncation
Output:
You entered the sentence Hello World
The number of words in the sentence is 11
The numner of vowels in your sentence is 3
The percentage of vowels is 27%

You are not using correct operator. modulus(%) gives you the remainder after the division. You need to use division (/) operation. You may want to use double/float for getting accurate value.
