再通过方法getGenericParameterTypes获取形参泛型类型:===");//输入方法名和参数的类列表,获取具体方法的反射Method fxMethod = cls.getDeclaredMethod("fanxingMethod", Map.class, String.class);//设置private类型方法可访问fxMethod.setAccessible(true);//获取所有参数类型列表Type[] parameterTypes =fxMethod.get...

>parameter, which represents a class of any type. Hence, we pass different classes (String.class,Integer.class,Double.class) to demonstrate the flexibility of this approach. 4. Reflection One common application of passing a class as a parameter is inreflection, where classes are dynamically loade...
Class Loader- Previously, it was possible to specify a non-binary class name toClassLoadermethods that take aStringclass name argument. This unintended behaviour was not compliant with the long-standing specification of class names. As of 5.0, parameter checking of theseClassLoadermethods has been...
The code, new OrderedPair<String, Integer>, instantiates K as a String and V as an Integer. Therefore, the parameter types of OrderedPair's constructor are String and Integer, respectively. Due to autoboxing, it is valid to pass a String and an int to the class. As mentioned in The Di...
The following is a generic version of it that accepts, as a parameter, a collection that contains elements of any data type:public static <X, Y> void processElements( Iterable<X> source, Predicate<X> tester, Function <X, Y> mapper, Consumer<Y> block) { for (X p : source) { if ...

A parameterized type like List<String> is itself a type and can be used as the value of a type parameter for some other type. You might see code like this: // Look at all those nested angle brackets! Map<String, List<List<int[]>>> map = getWeirdMap(); // The compiler knows al...
