Java other special Operators
The dot (.) operator is used to select members of a class or object instance:...
int i = myObject.length; //Retrieve the value of an instance variable
//(of an object) or a static variable (of a class).
myObject.someMethod( ); //A method to be invoked on an object or class
......
Object o = new Object( ); // o has reference to new object
// of Object type (class)
int hours = new Date().getHours(); // create a new object and invoke a
// method in it without assigning the object
......
Boolean b;
String str = "foo";
b = ( str instanceof String ); // true, str is a String
b = ( str instanceof Object ); // also true, as String is an Object
b = ( str instanceof Date ); // false, str is not a Date or subclass
// of Date
