- Write True or False 1. A method must always return a value. 2. A break statement must always be present in a "switch" statement . 3. Declarations must appear at the start of the body of a Java method. 4. An array in the Java has the ability to store many different types of values. 5. All variables must be declared before they can be used. إجابتكWhich of the following is true about the way method parameters are passed in Java? (select all that apply): ☐ (a) Arrays cannot be passed as parameters. (b) The invoked method receives a copy of passed references which can be modified (reassigned) by the method, but the original references in the calling code block will never be changed. (c) The called method can invoke accessible methods that a passed reference/object has to offer. (d) Parameters can be passed "by address" - exactly how address pointers are used in C++.Write a Java class in which you include the following: 1. A main method that: a. Declares a-one dimensional array of 10 integer elements. b. Asks the user to fill the array. c. Ask the user to enter an integer x. d. Calls the method in question 2. e. Print the result of the method. 2. A java method named "find" that accepts a one-dimensional array as a first parameter, and an integer x as a second parameter. The method should find and return the number of occurrences of x in the array.
- JAVA Method Overloading is a feature that allows a class to have more than one method having the same name, if their argument lists are different. Design a simple class and define a maximum method that finds the maximum of two integer values? Design an application to test that your new method is working properly. Now overload the maximum method to accept three double values and return the maximum of these three values? Finally overload the maximum method again such that it accept four double or four integer values and return the average of these four values? Modify your main( ) application to call and test these new methods. In each case the maximum overloaded methods should return the correct maximum values. Attach you java source codes and a screenshot of the output(s).Create the Median class that has the method calculateMedian that calculates the median of the integers passed to the method. Use method overloading so that this method can accept anywhere from two to five parameters. CODE: import java.util.Arrays; //add class definitions below this line //add class definitions above this line public class Exercise4 { public static void main(String[] args) { //add code below this line //add code above this line }}Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
- In Java, you have the opportunity to either use a predefined function/method or write a user-defined function/method. In this discussion, provide at least three criteria that would be used to develop an appropriate method of your choice and the rationale behind the selection of these criteria. Then provide an example of your method declaration and return type.Question Two Write a java program that prints student's name, grades and GPA. You must do the following requirements: 1. Create three methods: a. First method to accept and print your first, last name, and GPA. 2. Call the three methods you created above in your main method. b. Second method Markt and print your grades Marks of three courses (type: int) 3. Create a method without parameters that would return only your GPA. The method should be named with your last name followed by GPA (e.g., AlwalledGPA()). Note: c. Third method to overload the second method (types: double). The method must print your grades. 4. Declare a double variable that holds the returned value of the last method you created. 5. Print the value of your GPA variable. Help ● The class name of your Java program must be your first name. • Your answer should have the code as text as well as the screenshot of the program output (using your own name) as a part of your answer. Otherwise, zero marks will be awarded.…Please answer the JAVA question below. Based on the below prices double array, create a method call and method that passed in the prices array and determines which value is the lowest. double[ ] prices = {75, 25, 35, 150, 69.99};
- The file Parameters.java contains a program to test the variable-length method average.1. Read the code. Fill in the code to compute mean1 and mean2. Notice that you are calling the same method, but with a different number of parameters. 2. Add a call to find the average of a single integer, say 8. Print the result of the call. Is the result what you expected?3. Add a call with an empty parameter list and print the result. Is the result what you expected?4. Add a method called minimum to return the minimum value of the parameter list. Invoke this method in the main() and test it with different input numbers. //*******************************************************// Parameters.java//// Illustrates the concept of a variable parameter list.//*******************************************************import java.util.Scanner;public class Parameters{ //----------------------------------------------- // Calls the average and minimum methods with // different numbers of parameters.…in java: import java.util.Arrays;public class Assignment7 {/*** You do NOT need to make any changes to the main method.

Is it OK to declare two methods with the same name but distinct argument types? Is it legal to declare two methods in a class with similar method names and argument lists but distinct return value types or modifiers?
