Java Programming.  Trace through the method and determine what it does. Also draw the activation record. Thanks   1. What (2) public static int what (int x) { if (x <= 0) throw new IllegalArgumentException(); if (x == 1) return 0; int temp = what (x / 2); return 1 + temp; }

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

Code completion and explain.  public class X {      public static void main(String [] args)     {        try         {            badMethod();              System.out.print("A");          }         catch (RuntimeException ex) /* Line 10 */        {             System.out.print("B");         }         catch (Exception ex1)         {             System.out.print("C");         }         finally         {            System.out.print("D");         }         System.out.print("E");     }     public static void badMethod()     {         throw new RuntimeException();     } }.

Please help me with my assignment for computer science as I had all the dialog box pop up for me except for "Whew"  what am I doing wrong?  I am including with this message the coding block for the assignment.   import java.awt.event.*;import javax.swing.*;public class MouseWhisperer extends JFrame implements MouseListener {MouseWhisperer() {super("COME CLOSER");setSize(300,100);setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);addMouseListener(this);setVisible(true);}public void mouseClicked(MouseEvent e) { setTitle("OUCH"); }public void mousePressed(MouseEvent e) { setTitle("LET GO"); }public void mouseReleased(MouseEvent e) { setTitle("WHEW"); }public void mouseEntered(MouseEvent e) { setTitle("I SEE YOU"); }public void mouseExited(MouseEvent e) { setTitle("COME CLOSER"); }public static void main(String[] args) { new MouseWhisperer(); }}   Please advice.

Correct and detailed answer will be Upvoted else downvoted. Thank you!

Create a UML class diagram of the application illustrating class hierarchy, collaboration, and the content of each class. There is only one class.  There is a main method that calls four methods.  I am not sure if I made the UML Class diagram correct. import java.util.Random; // import Random packageimport java.util.Scanner; // import Scanner Package public class SortArray{ // class name public static void main(String[] args) { //main method Scanner scanner = new Scanner(System.in); // creates object of the Scanner classint[] array = initializeArray(scanner); System.out.print("Array of randomly generated values: ");displayArray(array); // Prints unsorted array sortDescending(array); // sort the array in descending orderSystem.out.print("Values in desending order: ");displayArray(array); // prints the sorted array, should be in descending ordersortAscending(array); // sort the array in ascending orderSystem.out.print("Values in asending order: ");displayArray(array); // prints the…
