Count Vowels from a String, Use Constructor

Write a Java Program to Count the Number of Vowels in a given string. Use Constructor, Instances and Method, if necessary. Do not use any parameter with Constructor.

ch == 'E' || ch == 'I' || ch == 'O' ||
ch == 'U')
count++;

}
System.out.println("Enter String is " + str);
System.out.println("Number of vowel of "+str+ " is : " + count);
}
}

public class vowel{
