CSCI 202: Object-Oriented Programming

Programs designed in class

• Adding Drawable interface to the hierarchy of shapes: Shape.java, Rect2.java and Circ2.java
• Drawing shapes
  • First approach: DrawShapes1.java     try it
  • Second approach: DrawShapes2.java     try it
  • Third approach: DrawShapes3.java     try it
• Comparing shapes
  • Making Circ3.java and Rect3.java implement interface Comparable
  • A better approach by using the Java 5 generics: Circ4.java and Rect4.java
  • Comparing shapes: TestShapes3.java
  • Sorting circles: SortCircs.java
  • Same task by using interface Comparator: SortCircs2.java
  • Searching an array of objects: SearchObj1.java
  • Same task by using the Java 5 generics: SearchObj2.java
  • Same task by using the method binarySearch of class Arrays: SearchObj3.java
• Cloning objects
  • A trivial approach: CloneShapes1.java
  • Implementing interface Cloneable: CloneShapes2.java
  • Checking if an interface is implemented by a class: CheckInterface.java
• Processing Timer events
  • First approach (based on the ActionListener interface and javax.swing.Timer class): TimerTest1.java
  • Second approach (based on the Runnable interface and java.util.Timer class): TimerTest2.java
  • Third approach: using anonimous inner class: TimerTest3.java
• Interface inheritence: Itest.java
• Using keyword final: final class, final method, final field (constant), final method parameter
