Modify the NumbersDemo application whose main() method holds two integer variables. Assign values to the variables.
In turn, pass each value to methods named displayTwiceTheNumber(), displayNumberPlusFive(), and displayNumberSquared().
Create each method to perform the task its name implies.
public class NumbersDemo {
public static void main (String args[]) {
// Write your code here
}
public static void displayTwiceTheNumber(int n) {
// Write your code here
}
public static void displayNumberPlusFive(int n) {
// Write your code here
}
public static void displayNumberSquared(int n) {
// Write your code here
}
}
In C# Which is the right way to call the displayIt method?private void displayIt (int x) { }
Question 4 options:
displayIt("5");
displayIt(5);
displayIt(int 5);
displayIt();
Modify the class named FormLetterWriter that includes two overloaded methods named displaySalutation(). The first method takes one String parameter that represents a customer’s last name, and it displays the salutation Dear Mr. or Ms. followed by the last name. The second method accepts two String parameters that represent a first and last name, and it displays the greeting Dear followed by the first name, a space, and the last name. After each salutation, display the rest of a short business letter using the displayLetter method: Thank you for your recent order.
An example of the program is shown below:
Dear Mr. or Ms. Kelly,
Thank you for your recent order.
Dear Christy Johnson,
Thank you for your recent order.

- Create a class IndependenceUSA and write code which asks the user to enter text that contains the American Independence day ( July 4th 1776). Read the date using the method next() 3 times. The user should enter the Independence day in the order month, day, year as shown in the first two runs below( we are not case sensitive) . Use the String method compareToIgnoreCase() to test the validi-ty of the date and print “Hurrah!” if the date entered is correct, or “No, no , no! Incorrect!” if the date incorrect is incorrect, or of the date entered in the wrong order. In other words, you compare your input to “July” , “4”, “1776” , in that order and you don't case for capital or small case letters.arrow_forwardWhich of the following statements are true about static methods.? Static methods do not need an object in a class to be invoked. Math.sin(x) is an example of a static method. Inside a class, a static method belonging to the class can be invoked by using its name. Outside a class, a static method is invoked by using the name of the class - like Math,pow. All of the above are true statements about static methods.arrow_forwardThis is java question: Create a class named Bottle, which contains the following attributes: isFull (boolean), drinkType (ex: water), fillLevel (max: 100). Then, create a method called drink, which takes an argument of how much liquid the user drinks. When the user calls drink, subtract the amount drank from the fillLevel and make sure that isFull is set to false. Lastly, create a constructor that initializes the object as a full bottle containing water.arrow_forward
- this is needed in Java Given a void method named storeData that has a double parameter, call the method using a double variable named myData as the argument. Assume that myData is already declared and initialized.arrow_forwardIn Java, all arguments are transferred to a method via value call (call by value)? Choose one of the options:TrueFalsearrow_forwardCreate a class named Percentages whose main() method holds two double variables, and prompt the user for values. Pass both variables to a method named computePercent() that displays the two values and the value of the first number as a percentage of the second one. For example, if the numbers are 2.0 and 5.0, the method should display a statement similar to: 2.0 is 40 percent of 5.0. Then call the method a second time, passing the values in reverse order. An example of the program is shown below: Enter a double >> 3.7 Enter another double >> 12.3 3.7 is 30.081300813008127 percent of 12.3 12.3 is 332.43243243243245 percent of 3.7 Task 01: Create the Percentages class. Task 02: The computePercent() method displays the percent of the first argument of the second argument. Task 03: The Percentages program accepts 2 double values from the console and displays the percent of first value of the second value and vice versa.arrow_forward
- Create a class called Complex for performing arithmetic with complex numbers. Complex numbers have the form realPart + imaginaryPart * i where i is -1 Write a program to test your class. Use floating-point variables to represent the private data of the class. Provide a constructor that enables an object of this class to be initialized when it is declared. Provide a no-argument constructor with default values in case no initializers are provided. Provide public methods that perform the following operations: a) Add two Complex numbers: The real parts are added together and the imaginary parts are added together. b) Subtract two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand, and the imaginary part of the right operand is sub- tracted from the imaginary part of the left operand. c) Print Complex numbers in the form (a, b), where a is the real part and b is the imaginary part.arrow_forwardComplete all the following questions as they are both linked altogether: 4.

Create 2 overloaded methods named computeCommission(). The first method takes 2 double arguments representing sales and rate, multiplies them and then displays the results. The second method takes 2 arguments: a double sales figure and an integer commission rate. This method must divide the commission rate by 100.0 before multiplying by the sales figure and displaying the commission. Supply appropriate values for the variables.
