- Method Overloading is a feature that allows a class to have two or more methods having same name, if their argument lists are different. Argument lists could differ in: 1. Number of parameters. 2. Data type of parameters. 3. Sequence of Data type of parameters. Write different version of method sum() that display the sum of the values received as parameter according to the following main method content: public static void main(String[] args) { sum ( 10, 10 ); sum ( 10, 10, 10 ); sum ( 10.0, 10.0 ); sum ( 10, 10.0 ); sum ( 10.0, 10); } You have to define five functions with the specified types. Then, demonstrate the Argument Promotion concept by reducing the number of method to two.Arrays are passed to methods by value; not by reference. True FalseJava: Class: SortedNumbers Write a method for the method header below and provide a (main) program to test it: boolean sorted(double x, double y, double z), returning true if the arguments are sorted, with the smallest one coming first Remember to include the Javadoc comment for the method.
- In Java, method overloading means that a program may contain more than one method with same signatures. Each column in a 2D array could be dealt with as 1D array.*In Java Problem Description and Given Info Write a public static method named countGreaterThanAverage that will take an int array as it's only argument. This method will return an int value. When called, and passed an array of int values, this method will compute and return the number of values in the argument array that are greater than the average of all the values in the argument array. Here are some examples: Example 1 Given: int[] myArray = {1, 2, 3, 4, 5}; countGreaterThanAverage(myArray) should return 2 Example 2 Given: int[] myArray = {13, 7, 6, 5, 99, 10, 4, 8}; countGreaterThanAverage(myArray) should return 1 Example 3 Given: int[] myArray = {1, 1, 1}; countGreaterThanAverage(myArray) should return 0 Helpful Info: You may want to write a main method to call and test your required method There should be no System.out.print or System.out.println statements in your countGreaterThanAverage method There should be no calls to any Scanner methods (like next, nextLine, or…Given the following: #includ int a[] ={4, 6}, i = 0, y =3, z =1; void f(int x){ int z = 2; g (); X = x + y; z = z +X; i++; return x + a[ i ]+y; } void g(){ z += 3; y = a[i] + z; } void main(){ printf("%d", y + f( a[i] ) - y); } State the output assuming the following: A) Call by reference, dynamic scoping, operands are evaluated right to left. B) Call by name, static scoping; operands are evaluated left to right.
- class overload { int x; double y; void add(int a , int b) { x = a + b; } void add(double c , double d) { y = c + d; } overload() { this.x 0; %3D this.y = 0; } %3D } class Overload_methods { public static void main(String args[]) { overload obj int a = 2; double b - 3.2; obj.add(a, a); obj.add(b, b); System.out.println(obj.x + } = new overload(); + obj.y); } #3Run the codePLZ help with the folllowig IN JAVA TRUE OR FALSE When a recursive call is encountered, computation is temporarily suspended; all of the information needed to continue the computation is saved and the recursive call is evaluated. 2.Can you have a static method in a nonstatic inner class?java If a recursive method does not have a stop case, what will happen ? System stops the program after a specified time After 1000 calls it will be stopped by the Java running machine An infinite loop will occur The program will throw an exception
- a Java static method that will take an array of strings as its only parameter. The method will return the first string alphabetically (lowest) in the array.Problem 1: Create a Java class RecursiveMethods.java and create the following methods inside: ALL THE METHODS NEED TO BE COMPLETED RECURSIVLY. NO LOOPS ALLOWED. oddEvenMatch Rec: the method takes an integer array as a parameter and returns a boolean. The method returns true if every odd index contains an odd integer AND every even index contains an even integer(0 is even). Otherwise it returns false. sumNRec: The method takes an integer array A and returns the sum of all integers in the parameter array. nDownToOne: Takes an integer n and prints out the numbers from n down to 1, each number on its own line. inputAndPrintReverse: Inputs integers from the user until the user enters 0, then prints the integers in reverse order. For this method, you may NOT use an array or any type of array structure, in other words, you may not use any structure to store the user input. After completing the methods, use the main method to test them. You can hard code the tests.True or False? In Java, an array of more than two dimensions cannot be declared.
