Java 反射，调用类的静态方法

【转】

  Class c;
c = Class.forName("class name");
Method m = c.getMethod("method name", new Class[] {int.class, int.class, int.class,int.class});
m.invoke(c, new Object[] {1,2, 3, 4});

【例子】

 

public class T {
    public static void aa(String t){
        System.out.println(t+"T");
    }
}

public class Test { 	public static void main(String[] args) throws ClassNotFoundException, SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException { 		Class c; 		c = Class.forName("K"); 		Method m = c.getMethod("aa", new Class[] {String.class}); 		m.invoke(c, new Object[]{"test"}); 	} }
