Which of the following is false in reference to static in java? A static variable is common to all the instances (or objects) of the class. O A static class cannot access non-static members of the Outer class. O A class can be made static only if it is a nested class. Static Methods can access class variables without using object of the class.

Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.

public class Cat { private int age; public Cat (int a) { age = а; } public int getAge() { return a; } } Which of the following best explains why the getAge method will NOT work as intended? The instance variable age should be returned instead of a, which is local to the constructor. The variable age is not declared inside the getAge method. The getAge method should be declared as private. The getAge method should have at least one parameter.
D: A 21. The method finalize automatically executes when the class object goes out ofI Scope. 22. A mutator method ofa class changes the values of the data members of the class. 23. In Java, the reference this is used to refer to only the methods. not the instance variables of a class.
Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have:  a constructor that accepts arguments for the two fields  a method that returns the tract’s area(i.e. length * width)  an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false.  a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…
1. For methods parameters are specified in the method definition, arguments are provided during a method call arguments are specified in the method definition, parameters are provided during a method call arguments override parameters parameters encapsulate arguments 2 Local variables are not automatically initialized. True False 3 Composition refers to an 'is-a' relationship. True False 4 Class constructors must be declared with a return type equal to the class.
