Object Oriented and Concurrent Programming in Java

[ an obj | an obj with d.b. | six objs | six objs with d.b. | sync. vs async. | Bounded buffer | Japanese ]

o Rotating an object

This 3D object is created directly using simple classes.
  1. Go
  2. Sample.html
  3. Sample.java
  4. WireFrame.java
  5. FreeSoR.java

In the next version, it can be processed using the double bufferings, then you can see it smoothly.

  1. Go
  2. Sample05.html
  3. Sample05.java

o Rotating objects

These 3D objects are created and executed concurrently. We create six objects on the screen.
  1. Go
  2. Sample1.html
  3. Sample1.java
  4. TR.java
The same additional bufferings are processed above programs.
  1. Go
  2. Sample15.html
  3. Sample15.java

o Synchronous v.s. Asynchronous

Using semaphores, it can be controled and changed its status by a button `Sync'. This version already includes the mechanism of double bufferings.
  1. Go
  2. Sample2.html
  3. Sample2.java

o Bounded Buffers

This applet emulates a bounded buffer. At first, the following one does not include double bufferings.
  1. Go
  2. Sample3.html
  3. Sample3.java
The other version of bounded buffer.
  1. Go
  2. Sample4.html
  3. Sample4.java
