利用反射获取Java类中的静态变量名及变量值的简单实例

java可以通过反射获取成员变量和静态变量的名称，局部变量就不太可能拿到了。

public class test {

  public static void main(string[] args) throws exception {
    // todo auto-generated method stub
    //获取所有变量的值
    class clazz = class.forname("com.qianmingxs.scoretable");
    field[] fields = clazz.getfields();

    for( field field : fields ){
      system.out.println( field.getname() + " " +field.getint(clazz) );
    }
    //获取单个变量的值
    /*class clazz = class.forname("com.qianmingxs.scoretable");
    field field = clazz.getfield("five");
    system.out.println( field.getint(clazz));*/
  }

}

其中要查看的java类是：

public class scoretable {
  private scoretable() {}
  public final static int five = 100;//成5
  public final static int double_alive_four = 99;//双活4(分析对手用)
  public final static int alive_four_and_dead_four = 98;//活4死4(对手分析用)
  public final static int alive_four_and_alive_three = 96;//活4活3(分析对手用)
  public final static int alive_four_and_dead_three = 95;//活4死3(分析对手用)
  public final static int alive_four_and_alive_two = 94;//活4活2
  public final static int alive_four = 93;//活4
  public final static int double_dead_four = 92;//双死4
  public final static int dead_four_and_alive_three = 91;//死4活3
  public final static int dead_four_and_alive_two = 90;//死4活2
  public final static int double_alive_three = 80;//双活3
  public final static int alive_three_and_dead_three = 70;//活死3
  public final static int half_alive_four = 65;//半活4(类似○○ ○形),优先级小于活4
  public final static int alive_three = 60;//活3
  public final static int dead_four = 50;//死4
  public final static int double_alive_two = 40;//双活2
  public final static int dead_three = 30;//死3
  public final static int alive_two = 20;//活2
  public final static int dead_two = 10;//死2
  public final static int single = 0;//单个
}
