public boolean isSynthetic();

判断方法是否是合成方法

注：桥方法必是合成方法，因为其是由JDK编译时生成的

下面这段代码就生成了一个合成方法

public class TestSynthetic {
    @Test
    public void testSynthetic() {
        Method
        [] methods = User.class.getDeclaredMethods();
        //这里实现化user对象时调用了私有构造器
        User user = new User();
        //这里也访问了私有变量
        user.age = 1;
        for (Method method : methods) {
            System.out.println(method.toString() + "," + method.isSynthetic() + method.isBridge());
        }
    }
    class User {
        private int age;
        private String name;

        private User() {

        }

        private User(int age, String name) {
            this.age = age;
            this.name = name;
        }

        private int getAge() {
            return age;
        }

        private void setAge(int age) {
            this.age = age;
        }

        private String getName() {
            return name;
        }

        private void setName(String name) {
            this.name = name;
        }
    }
}
