In Java Write a Fraction class that implements these methods:• add ─ This method receives a Fraction parameter and adds the parameter fraction to thecalling object fraction.• multiply ─ This method receives a Fraction parameter and multiplies the parameterfraction by the calling object fraction.• print ─ This method prints the fraction using fraction notation (1/4, 21/14, etc.)• printAsDouble ─ This method prints the fraction as a double (0.25, 1.5, etc.)• Separate accessor methods for each instance variable (numerator , denominator ) in theFraction classProvide a driver class (FractionDemo) that demonstrates this Fraction class. The driver class shouldcontain this main method : public static void main(String[] args) { Scanner stdIn = new Scanner(System.in); Fraction c, d, x; // Fraction objects System.out.println("Enter numerator; then denominator."); c = new Fraction(stdIn.nextInt(), stdIn.nextInt()); c.print(); System.out.println("Enter numerator; then denominator."); d = new…

Write, compile, and test a class that uses the command window to display the following statement about comments: Program comments are nonexecuting statements you add to a file for documentation. Also include the same statement in three different comments in the class; each comment should use one of the three different methods of including comments in a Java class.

Object-Oriented Programming OvalDraw Plus (Java code) Summary: Create a graphical application with Java that that draws an oval Prerequisites: Java, VS Code, and Terminal Create a graphical Java application that runs on Microsoft Windows and MacOS that draws an oval centered in the main application window when the programming starts. The oval should automatically resize and reposition itself when the window is resized. In this activity you will start with our OvalDraw application in our sample code, review the code, and then make incremental improvements to the application. Be sure to make the resulting application uniquely your own by adding standard comments at the top application (i.e. your name, class, etc.), changing the names of variables, and adding small features. Finally, be sure to save your work as you will often be asked to submit it as part of an assignment. Be sure to review the example OvalDraw project in the Java section of our example code repository. Requirement 1:…

Develop a Shipping Calculator Java application, which contains the concepts of a Java object and class. This Java Program must include the declaration and definition of object and class.   The steps for the program are outlined below:   Create a Java class named Package that contains the following: Package should have three privateinstance variables of type double named length, width, and height.  Package should have one privateinstance variable of the type Scanner named input, initialized to in.  No-args(explicit default) public constructor, which initializes all three double instance variables to 1.0.   Initial(parameterized) public constructor, which defines three parameters of type double, named length, width, and height, which are used to initialize the instance variables of same name.  Public copyconstructor, with a parameter of type Package, used to duplicate an existing Package object.  Three public void methods named inputLength,inputWidth, and inputHeight. Each method will…
