- The following technique is used in a game of chess: canMoveTo(int x, int y), boolean. A method in the Piece class returns if the piece may travel to position (x, y). Describe how you would put this method to the test.Does a method have access to the original object or a copy of it when it receives an object as a parameter?JAVA HELP PLEASE! Write a class Rectangle that has only the following public methods (you can add other non-public methods if you think you need them): Write a constructor that creates a rectangle using the x, y coordinates of its lower left corner, its width and its height (the parameters must be in that order). Creating a rectangle with non-positive width or height should not be allowed; throw an IllegalArgumentException for those cases. The values of x and y are allowed to be negative. Write a method overlap(Rectangle other). This method should return true if this rectangle overlaps with other, false otherwise. Rectangles that touch each other are not considered to be overlapping. Write a method toString that returns a String. The string should be formatted exactly as:“x:2, y:3, w:4, h:5”without the quotation marks and replacing the numbers with the actual attribute values of the object. A class called Rectangle exists in Java already. You are not allowed to use this class in any…
- Write a method toString() for the Cow class which displays information about a Cow object. The method should consider the following: • If the Cow's stomach value is 100, the output should say that the Cow is full • If the Cow's stomach value is below 100 but above 50, no information about the Cow's stomach should be given • If the Cow's stomach value is below 50 but above 10, the output should mention that the cow is hungry • If the Cow's stomach value is below 10, the output should mention that the cow is starving. Example output: First Cow is full. Second Cow Third Cow is hungry. Fourth Cow is starving!A return statement is the same as a print statement. Anything that a method returns will automatically get printed. True FalseLook through the method header below, then, as an example, write a call to the method.an internal void ShowValue()
- Look through the method header below, then, as an example, write a call to the method. an internal void ShowValue()Look at the header of the method below, and then implement a sample call to it in your code.private static void ShowValue ()Exercise 2: The intersection method computes the intersection of two rectangles- that is, the rectangle that would be formed by two overlapping rectangles if they were drawn, as shown at right. You call this method as follows: Rectangle r3 = r1.intersection (r2); Write a program IntersectionPrinter that constructs two rectangle objects, prints them as described in Exercise 1, and then prints the rectangle Intersection object that describes the intersection. Then the program should print the result of the intersection method when the rectangles do not overlap. Add a comment to your program that explains how you can tell whether the resulting rectangle is empty. The random class implements a random number generator, which produces sequences of numbers that appear to be random. To generate random integers, you construct an object of the Random class, and then apply the nextInt (50) gives you a random number between 0 and 49. Use the Random class to construct the two rectangle objects.
