A class is created by use of the keyword class.

The general form of a class definition that contains only instance variables and methods:

class classname {
    // declare instance variables
    access type var1;
    access type var2;
    // ...
    access type varN;
    
    // declare methods
    access ret-type method1(parameters) {
        // body of method
    }
    access ret-type method2(parameters) {
        // body of method
    }
    // ...
    access ret-type methodN(parameters) {
        // body of method
    }
}

The general form for declaring an instance variable is shown here:

access type var-name;

1. access specifies the access,
2. type specifies the type of variable, and
3. var-name is the variable's name.

1. To access these variables, you will use the dot (.) operator.
2. The dot operator links the name of an object with the name of a member.
3. The general form of the dot operator is shown here:

object.member

You can use the dot operator to access both instance variables and methods.
