- 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.ln OOP perspective, it is nothing but an instance of a class that contains real values instead of variables.A.MethodB.VariableC.ClassD.ObjectWith comments, differentiate between static and non-static objects.

- Search for textbooks, step-by-step expl = bartleby e Q&A Library Design a class nam Start your trial Design a class named MyPoint to represent a point with X-and y-coordinates. The class contains: The data fields x and y that represent the coordinates with getter methods. A no-arg constructor that creates a point (0, 0). A constructor that constructs a point with specified coordinates. A method named distance that returns the distance from this point to a specified point of the MyPoint type. A method named distance that returns the distance from this point to another point with specified x- and y-coordinates. A static method named distance that returns the distance from two MyPoint objects. Draw the UML diagram for the class then implement the class. Write a test program that creates the two points (0, 0) and (10, 30.5) and displays the distance between them.
