An array of class objects can be created in Java. False or True

1 import java.util.Random; 2 3 4 5 6- 7 8 9 10 11 12 ▼ import java.util.StringJoiner; public class preLabC { public static MathVector myMethod(int[] testValues) { // Create an object of type "MathVector". // return the Math Vector Object back to the testing script. return VectorObject; 13 14 15 } } ▸ Comments Description The MathVector.java file contains a class (Math Vector). This class allows you to create objects in your program that can contain vectors (a 1D array) and perform actions on those vectors. This is useful for doing math operations like you would in your linear algebra class. Your method should evaluate against two tests. What do you need to do in this exercise? You need to create an "instance" of the MathVector object, VectorObject, in your method. If you do this correctly, your method will accept a 1D array of integers, testValues, feed it into the VectorObject and then return the VectorObject. If you look in the file MathVector.java you'll see that this is one way in...

Q1: Write the Java code corresponding to the following UML diagram. The class School implements the interface Building. The method computeArea returns the area of the building as width * length. After that, add a testing class with a main method which defines an arrayList that contains three objects. From the main method, print the area of all the three objects. Building> + computeArea() : double + toString() : String School classroomNum: int width: double - length: double + School(classroomNum: int, width: double, length: double) + computeArea() : double + toString() : String
