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.
10. public static void methodl (int i, int num) { for (int j = 1; j <= i; j++) { " "); System.out.print (num + num *= 2; } System.out.println(); } public static void main(String[] args) { int i = 1; while (i <= 6) { methodl (i, 2); i++; }
The UsingMethod class consists of a main method and a method called xMethod. Whatwill the code print? public class UsingMethod { public static void main(String[] args) { double z = xMethod(3.5, 5.5); System.out.println(z); } public static double xMethod(double x, double y) { return x + y; } }
Consider the following methods: public void inchesToCentimeters(double i) { double c = i * 2.54; printInCentimeters(i, c); } public void printInCentimeters(double inches, double centimeters) { System.out.print(inches + "-->" + centimeters); } Assume that the method call inchesToCentimeters(10) appears in a method in the same class. What is printed as a result of the method call? inches -> centimeters 10 -> 25 25.4 -> 10 10 -> 12.54 10.0 -> 25.4
