need help fix this Java code described below so that it can be followed in the image below   package classPackage;   import interfaces.RatInterface;   public class Rat implements RatInterface { private int ratEnergy = 5; @Override public String move() { // TODO Auto-generated method stub returnnull; }   @Override publicint getAliveState() { // TODO Auto-generated method stub return 0; }   @Override publicvoid refresh() { ratEnergy = 5; }   @Override publicvoid wearDown() { ratEnergy -= 1; }   @Override public String getId() { // TODO Auto-generated method stub returnnull

For this assignment, create a child class of car that creates a car of a randomly generated color. Using the existing car classes, add code to add 20 colored cars to the existing pane in 20 visible, random locations. You will end up with 4 classes: CarViewer.java CarComponent.java Car.java (unchanged from Chapter 3) ColorCar.java (extends Car)

Hi I want to create a JAVA program that will allow me to create a canvas (specifically in eclipse). Can someone straighten my code   import java.awt.*;import javax.swing.*;class Main extends JFrame {     // constructor    Main()    {        super("canvas");         // create a empty canvas        Main c = new Main() {             // paint the canvas            public void paint(Graphics g)            {                // set color to red                g.setColor(Color.red);                 // set Font                g.setFont(new Font("Bold", 1, 20));                 // draw a string                g.drawString("This is a canvas", 100, 100);            }        };         // set background        c.setBackground(Color.black);         add(c);        setSize(400, 300);        show();    }     // Main Method    public static void main(String args[])    {        Main c = new Main();    }}             ReplyForward

please write code in java Create a right triangle class with instance variables(double) for sideA, sideB and the hypo. write three constructors -the 2-param version assigns to sides A and B respectively. the 1-param version assigns the same value to both sides. the 0-param version assigns 10.0 to each side. the constructor also computes the hypotenuse based on the other two sides and saves that in the hypotenuse variable. Create accessors for all three variables. Write a toString() that will print/label the three sides. write some main code to create three instances of your class, one to test each of your constructors. you can input values or use fixed values. Display each instance using an implicit toString() call.
