Java泛型类、接口、方法的使用方法的全部案例

package com.Demo02.Generic; public class TestGeneric { public static void main(String[] args) { //使用泛型类创建对象 MyGeneric<String> myGeneric = new MyGeneric<String>(); myGeneric.t="hello"; myGeneric.show("hello world"); String string = myGeneric.getT(); MyGeneric<Integer> myGeneric1 = new MyGeneric<Integer>(); myGeneric1.t = 100; myGeneric1.show(20); Integer i = myGeneric1.getT(); //泛型接口 MyInterfaceImpl impl = new MyInterfaceImpl(); impl.server("xxxxxxx"); MyInterfaceImpl2<Integer> impl2 = new MyInterfaceImpl2(); impl2.server(1444); //泛型方法 类型有传递的数据决定 MyGenericMethod myGenericMethod = new MyGenericMethod(); myGenericMethod.show("hello world"); myGenericMethod.show(100); } }
