testfinal.java

有一个接口,用抽象类实现它的部分功能,再用实现类继承抽象类,实现其它没实现的接口方法

package cn.edu.csu.oo.finaloper;

final class FinalAttribute{
  final int count;
  int size;
  public int getSize(){
    return size;
  }
  public final void setSize(int size){
    this.size = size;
  }
  public FinalAttribute(){
    count = 1001;
  }
  public void setCount(){
//    count = 1001;
    final int i;
    i = 11;
  }
}
class FinalOper extends String{
//  public void setSize(int size){}
}
public class TestFinal {
  static final FinalAttribute fa = new FinalAttribute();
  
  /**
   * @param args
   */
  public static void main(String[] args) {
//    fa = new FinalAttribute();
    TestFinal tf = new TestFinal();
    tf.fa.setSize(12);
    System.out.println(tf.fa.getSize());
  }

}
