1. Methods in Java
2. Method Syntax
3. Calling Methods
4. Static Methods
What is a Method
Collection of statements grouped together
Identified by name
Can take multiple input parameters
Can return single output value
What are Functions and Procedures
All are alike, as they hold collection of statements
Used in different programming paradigms
Function and Methods usually return a value
What happens when method is called
Execution of program moves to body of that method
When finished executing method body, it returns to the area of program from where it was called
Java Method Syntax
access-modifier return-type method-name ( [ parameter list ] ) {
statement 1;
statement 2;
[ return return-value; ]
}
Access Modifiers : public, private and others that we will learn later
Static : static indicates that method belongs to the class
Return Type : data type of value returned by method or void for no value
Method Name : method names according to naming convention
Parameter List : input to the method
Static keyword makes method static
Static method belongs to the class
Static methods can be invoked without creating instance of class
