Create a new Java class with a main() method that displays "Hello World!" followed by a new line with your name on it. The final printout should look like: Hello, World! by

When comparing two objects using the equals method inherited from the Object class, what is actually compared is the contents of the objects in java. True or False

Write a class that instantiates a Scanner object and asks the user for their grade, represented by an integer, and then full name, represented by a String, (in that order specifically) on separate lines, and then prints it a string in the format given below with the user input printed. The output should look like below, with bold text in brackets representing user input. Grade: [11] Name: [John Smith] Welcome John Smith, you are in grade 11!

2. Modify the Fahrenheit program so that it displays a button that when pressed causes theconversion calculation to take place. The user will have the option of pressing Enter inthe text field or pressing the button. Have the listener that is already defined for the textfield also listen for the button push.

How do I write this in Java programming using Scanner class? There are 12 inches in a foot and 3 feet in a yard. Create a class named InchConversion. Its main() method accepts a value in inches from a user at the keyboard, and in turn passes the entered value to two methods. One converts the value from inches to feet, and the other converts the same value from inches to yards. Each method displays the results with appropriate explanation. This is what it starts with: import java.util.Scanner; public class InchConversion {     public static void main (String args[]) {         //Enter code here } public static void convertToFeet(int inches) {        //Enter code here }public static void convertToYards(int inches) {        //Enter code here

In Java please. Only aswer the code where it says  "/* Your code goes here */". Write a method lastNameFirst that takes a string containing a name such as "Harry Smith" or "Mary Jane Lee", and that returns the string with the last name first, such as "Smith, Harry" or "Lee, Mary Jane". import java.util.Scanner; public class Names{   /**      Changes a name so that the last name comes first.      If name has no spaces, it is returned without change.      @param name a name such as "Mary Jane Lee"      @return the reversed name, such as "Lee, Mary Jane".    */   public static String lastNameFirst(String name)   {       /* Your code goes here */    }      public static void main(String[] args)   {      Scanner in = new Scanner(System.in);      String name = in.nextLine();      System.out.println(lastNameFirst(name));   }}

Use Java program to add a method printReceipt to the CashRegister class. The method should print the prices of all purchased items and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information.  Here is the CashRegister class: /**   A cash register totals up sales and computes change due.*/public class CashRegister{   private double purchase;   private double payment;    /**      Constructs a cash register with no money in it.   */   public CashRegister()   {      purchase = 0;      payment = 0;   }    /**      Records the sale of an item.      @param amount the price of the item   */   public void recordPurchase(double amount)   {      purchase = purchase + amount;   }    /**      Processes a payment received from the customer.      @param…
