TAILIEUCHUNG - Lecture Software construction - Lab 3: Classes and objects in java

In this chapter, the following content will be discussed: Introduce to classes and objects in Java, understand how some of the OO concepts learnt so far are supported in Java, understand important features in Java classes. | Software Construction Lab 3 Classes and Objects in Java Basics of Classes in Java Contents Introduce to classes and objects in Java. Understand how some of the OO concepts learnt so far are supported in Java. Understand important features in Java classes. Classes A class is a collection of fields (data) and methods (procedure or function) that operate on that data. Circle centre radius circumference() area() Classes A class is a collection of fields (data) and methods (procedure or function) that operate on that data. The basic syntax for a class definition: Bare bone class – no fields, no methods public class Circle { // my circle class } class ClassName [extends SuperClassName] { [fields declaration] [methods declaration] } Adding Fields: Class Circle with fields Add fields The fields (data) are also called the instance varaibles. public class Circle { public double x, y; // centre coordinate public double r; // radius of the circle } Adding Methods A class .
