static String recording(String name){ // parameterized method - recording
return name;
}

public static void main(String[] args) { //main method

calling(); // static method can be called without creating an object

Phone nokia = new Phone();
nokia.playing(); // non static method can be called only by creating object

System.out.println(recording("video")); //argument inside bracket
}
}
A method is a block of code that performs a specific task.
returnType - It specifies what type of value a method returns For example if a method has an int return type then it returns an integer value.

If the method does not return a value, its return type is void.
methodName - It is an identifier that is used to refer to the particular method in a program.
method body - It includes the programming statements that are used to perform some tasks. The method body is enclosed inside the curly braces { }.
To call a method, write the method's name followed by two parentheses () and a semicolon;
static method can be accessed without creating an object
non static method can be accessed by creating an object

While defining a method, remember that the method name must be a verb and start with a lowercase letter. If the method name has more than two words, the first name must be a verb followed by adjective or noun. In the multi-word method name, the first letter of each word must be in uppercase except the first word. For example:
Single-word method name: sum(), area()
Multi-word method name: areaOfCircle(), stringComparision()
