A method is a collection of statements that perform an operation. It has a method header with the modifier, return type, name and parameters. The method body contains the statements that define what the method does. Method overloading allows methods to have the same name but different parameters, allowing methods to execute differently based on the parameters passed. In the example, the Addition method is overloaded with two versions - one taking two ints and one taking three ints. When called with different numbers of arguments, the appropriate overloaded method is executed.

![public static void main(String[] args)
{
int Answer1 = Addition(5, 6);
// In this case Method 1 will be called
System.out.println(Answer 1 = + Answer1);
int Answer2 = Addition(5, 6, 7);
// In this case Method 2 will be called
System.out.println(Answer 2 = + Answer2);

- 1. Presented by MD. TOFAZZAL HOSSAIN ID NO: 163015003 Department: CSE (Weekend)
- 4. A collection of statements that are grouped together to perform an operation. A method has the following syntax modifier return_Value_Type Method Name(list of parameters) { // Method body; } A method definition consists of a method header and a method body
- 5. Method Name The actual name of the method. Method name and the parameter list together constitute the method signature. Parameters This value is referred to as actual parameter or argument. The parameter list refers to the type, order, and number of the parameters of a method.
- 6. Method Body The method body contains a collection of statements that define what the method does.
- 7. A concept in Java which allows programmer to declare method with same name but different behavior. Method with same name co-exists in same class but they must have different method.
- 8. If you have two methods with same name in one Java class with different method. Generally overloaded method in Java has different set of arguments to perform something based on different.
- 9. public class MethodOverLoading { // Method 1 public static int Addition(int a, int b) { System.out.println(Method 1 is called); return a + b; } // Method 2 public static int Addition(int a, int b, int c) { System.out.println(Method 2 is called); return a + b + c; } }
- 10. public static void main(String[] args) { int Answer1 = Addition(5, 6); // In this case Method 1 will be called System.out.println(Answer 1 = + Answer1); int Answer2 = Addition(5, 6, 7); // In this case Method 2 will be called System.out.println(Answer 2 = + Answer2); }
- 11. Method 1 is called Answer 1 = 11 ---------------------------- Method 2 is called Answer 2 = 18
