arraydefine.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.programmer;

public class ArrayDefine {

  /**
   * @param args
   */
  public static void main(String[] args) {
    TempArray[] temp = new TempArray[3];
    temp[0] = new TempArray(11,"temp1");
    temp[1] = new TempArray(12,"temp2");
    temp[2] = new TempArray(13,"temp3");
//    temp[3] = new TempArray(14,"temp3");
    new ArrayDefine().printReferArray(temp);
  }
  public void printReferArray(Object[] obj){
    for(int i = 0; i < obj.length;i++){
      System.out.println(obj[i]);
    }
  }
  public void printArray(int[] obj){
    int sum = 0;
    for(int i = 0; i < obj.length; i++){
      sum += obj[i];
    }
    System.out.println(sum);
  }
}
