Person類里有這個方法public class Person {String shenjingbing(int a,boolean b,double d) {?? ??? ?return null;?}}為什么執行這段代碼會間歇性的報錯呢，有時又可以運行。try {?? ??? ??? ?System.out.println(Person.class.getMethod("shenjingbing", int.class,boolean.class,double.class).toString());//上面換成包裝類.class也一樣?? ???? } catch (NoSuchMethodException e) {?? ??? ??? ?// TODO Auto-generated catch block?? ??? ??? ?e.printStackTrace();?? ??? ?} catch (SecurityException e) {?? ??? ??? ?// TODO Auto-generated catch block?? ??? ??? ?e.printStackTrace();?? ??? ?}
