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
}
