1) Predict the output of the following code: public class MyClass extends Test { public static void main(String[] args) { MyClass x = new MyClass(); Test y = new MyClass(); System.out.println(x.num() + " " + y.num()); } public static int num() { return 2; } } class Test { public static int num() { return 5; } } a. Runtime error b. 22 c. 2 5 d. Compilation error

Please give me the solution

what is the output? public class practice {     public static void main(String[] args)     {         new ChildClass(5).tryThis(4);     } } class ParentClass {     public ParentClass(int i)     {        System.out.print(i); //notice the ln is missing     } } class ChildClass extends ParentClass {       int a;     public ChildClass(int a)     {        super(a + 3);        this.a = a;     }       public void tryThis(int a)     {               System.out.print(a);     } }

Given the following class definition,public class Pen{  private String name;  public Pen(String n)   {      name = n;  }    @Override   public String toString()   {        return this.name + "-";  }}public class Brush extends Pen{   private int ink;   public Brush(String n, int m)   {      super(n);        ink = m;   }   @Override  public String toString()  {        return super.toString() + this.ink + "-";  }}What is the output of the following program?      Brush fluffy = new Brush("Fluffy", 5);      System.out.print(fluffy);If there is no output, please specify "nothing" (no quotes) in the blank for the output.    No hand written and fast answer with explanation

Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works.  Next add the following public methods to the Address class and test them from main as you go: Write getters and…

Please help debug this: Debugging Exercise 4-3, Farrell, Joyce, Java Programming, 9th edition, Cengage Learning public class DebugBox { private int width; private int length; private int height; private FixDebugBox() { length = 1; width = 1; height = 1; } public DebugBox(int width, int length, int height) { width = width; length = length; height = height; } public void showData() { System.out.println("Width: " + width + " Length: " + length + " Height: " + height); } public double getVolume() { double vol = length - width - height; return vol; } }

The following is in Java: public class MyClass {       private int x;       private double y;             public static void setValues(int a, double b)       {         x = a;          y = b;       } }   1) What is the problem? 2) In a few sentences how can the issue be fixed?
