Methods in Java
Methods:
(DRY)- don\t repeat yourself
the method in Java is a collection of instructions that performs a specific task.
Creating Methods:
Public static int methodName(int a, int b){ //body }The syntax shown above includes -
modifire | It defines the access type of the method and it is optional to use. |
returnType | Method may return a value. |
nameOfMethod | This is the method name. The method signature consists of the method name and the parameter list. |
Parameter List | The list of paramethers, it is the type, order,and number of parameters of a method. These are optional, method may contain zero parameters. |
method body | The method body defines what the method does with the statements. |
Example
public class Introduction {public static void main(String args[]) {int x = 34, y = 43;int result = maxOf(x, y);System.out.println(result + " is max");}static int maxOf(int a, int b) {if (a > b) {return a;} else {return b;}// return a > b ? a : b;}}
43 is maxMethod Overloading:
When a class has two or more methods by the same name but different parameters, it is known as method overloading
Ex.
int maxOf(int a, int b){ }
int maxOf(int a, int b, int c){ }
int maxOf(float a, float b){ }
