can you solve this please? Adopt appropriate Java animation code to implement the video in the file “test4.wmv” and given that the parametric equation for a circle. x=r*cos(t) y=r*sin(t) with t in range [0, 2p] and r is the radius of the circle. (the circle goes in a loop like in the images, i did my best to try to explain it , please try to do it ) and here is a sample of what they want me to use : package javaapplication1;import java.awt.*;import java.awt.event.*;import javax.swing.*;import java.awt.geom.*;import java.util.Random;import javax.imageio.*;import java.io.File;import java.io.IOException;import java.awt.image.BufferedImage;import java.awt.event.*;import java.util.Calendar; public class JavaApplication1 extends JApplet { public static void main(String[] args) { JFrame frame=new JFrame(); frame.setTitle("hello"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JApplet applete =new JavaApplication1(); applete.init();…

I'm unable to use the method replaceAll because we have not touch upon it yet, so since the chapter cover loops, here are my 2 codes (Code 1) import java.util.Scanner; public class LabProgram {public static void main(String[] args) {/* Type your code here. */Scanner scnr = new Scanner(System.in);String str= scnr.next();String newStr=""; for (int i=0; i < str.length(); i++) {if (str.charAt(i) == '@')newStr+="";else if (str.charAt(i) == '1')newStr+="";else if (str.charAt(i) == '!')newStr+="";else if (str.charAt(i) == '-')newStr+="";else if (str.charAt(i) == '$')newStr+="";else if (str.charAt(i) == '.')newStr+="";else if (str.charAt(i) == ' ')newStr+="";else newStr= str.charAt(i);}System.out.println(newStr); }} (Code 2) It's the same as the 1st code but I removed the charAt(i) to newStr as in: newStr=str; System.out.println(newStr); This code displayed the string but no nonalpha characters were removed.

Input a number n and print out n lines of text in the pattern below, shown for example n = 5 * * * * 1 * * * 2 1 * * 3 2 1 * 4 3 2 1 5 4 3 2 1 There is exactly one space between numbe4rs, there is no space at the end of each line, and each line ends with a newline. The first two tests will ignore the whitespace.
Please check images for the rest of the question and provide code with comments and explanations. Thank you. Write a set of static methods, to make console input simpler. Consider that the only console input method using the Scanner class is inputString(), shown below; include it in your solution. This means you are not permitted to use the Scanner class in any of your methods. public static String inputString (){Scanner scan = new Scanner (System.in); // attach to consolereturn ( scan.next() ); // return next string from input console stream}Example of calling and testing this method in your main():String str = inputString(); // get input from console, assign to strdisplayln ("Input A is: " + str); // display input stringdisplayln ("Input B is: " + inputString() ); // get input and display
I have already written the program and have it right, but I need help write print statement for the testorder class so that the display result looks as shown in the images. I am having trouble getting that right. I will paste the program below so you can run it and attatch the image of display result. Program for Order Class: package homework; import java.util.Date; public class Order { //Declare final variables public static final int ON_ORDER = 0; public static final int CANCELLED = 1; public static final int SHIPPED = 2; //Declare local variables private int totalOrder; private String orderName; private Date date; private int status; private String shippingAddress; private String phoneNumber; private String billingAddress; //Constructor public Order(String name) { this.totalOrder += 1; this.orderName = name; this.status = ON_ORDER; this.date = new Date();} //Cancel the placed order…
Please write the Java code for a Time class: Leave comments as explaination for how the code work, and finish the code.

I have a difficult task that i have been given, the problem is that I just simply cant seem to manage to first print a binary number so if you give me six my code doesnt seem to print the number in binary. but also i need to print it in reverse and my code just doesnt seem to work with that. heres my code import java.util.Scanner; public class LabProgram { public static void main(String[] args) { int x; int output; int i; Scanner input = new Scanner(System.in); x = input.nextInt(); output = x; for ( i = 0; i <= x; i = ++i){ output = x / 2; System.out.println(output); } } } // and bellow this are my instructions . what am i doing wrong what am i missing? ive googled sites and erased portions of code, put in eithers. ive switched back and forth from a for loop to a while loop for awhile now Write a program that takes in a positive integer as input, and…
Write a second convertToInches() with two double parameters, numFeet and numInches, that returns the total number of inches. Ex: convertToInches(4.0, 6.0) returns 54.0 (from 4.0 * 12 + 6.0). import java.util.Scanner; public class FunctionOverloadToInches { public static double convertToInches(double numFeet) {return numFeet * 12.0;} /* Your solution goes here */ public static void main (String [] args) {double totInches; totInches = convertToInches(4.0, 6.0);System.out.println("4.0, 6.0 yields " + totInches); totInches = convertToInches(5.8);System.out.println("5.8 yields " + totInches);}}
Is there a particular reason why I do not get the right answer after I choose my option? Entering student ID ( that was previously entered ) and then displayed something different?
