1. Assume you have a Car class that declares two private instance variables, make and model. Write Java code that implements a two-parameter constructor that instantiates a Car object and initializes both of its instance variables. 2. Logically, the make and model attributes of each Car object should not change in the life of that object. a. Write Java code that declares constant make and model attributes that cannot be changed after they are initialized by a constructor. Configure your...

Write a Java class (name it TwoNumbers) that will manage two numbers. The class should have two integer variables. The class should have the following constructors: - TwoNumbers(); - TwoNumbers(3, 4); The first constructor should initialize the class variables to zero. The second constructor should initialize the class variables to the passed variables. The class should have the following methods: - setNumbers(3, 4); - setFirstNum(3); - setSecondNum(4); - getSum(); - getDiff(); - getProd(); The setNumbers(3, 4) method should initialize the...

Write a class StringsAndThings. The class has one instance variable of type String and a constructor with a parameter to initialize the instance variable. The parameter could contain any characters, including letters, digits, spaces, special characters (+, -, $, @,...), and punctuation marks. Write methods: countNonLetters - that will count how many of the characters in the string are not letters. You can use Character's isLetter method. moreVowels - which returns true if the String parameter has more vowels than...
