- JAVA Practice Question for Midterm Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned. Imagine you are developing a software package for an online shopping site that requires users to enter their own passwords. Your software requires that users’ passwords meet the following criteria: The password should be at least six characters long. The password should contain at least one uppercase and at least one lowercase letter. The password should have at least one digit. a program that asks the user to enter a password, then displays a message indicating whether it is valid or not.import javax.swing.JOptionPane; public class Mileage { public static void main(String[] args) { String inputString; double miles; double gallons; double mpg; inputString= JOptionPane.showInputDialog("This program will calculate mileage"); miles =Double.parseDouble(inputString); inputString= JOptionPane.showInputDialog("Enter amount of miles driven:"); gallons =Double.parseDouble(inputString); mpg= (miles/gallons); JOptionPane.showMessageDialog(null, "Miles per gallon: "+ mpg); System.exit(0); }} hi, I will like to know how can I display the result "mpg", but with 2 decimals? What or how should I add to my code?
