JAVA利用泛型返回类型不同的对象方法

publicclassReturnTwo {

 publicfinalA first;

 publicfinalB second;

 publicReturnTwo(A a,B b) {

  first = a;

  second = b;

 }

}

publicclassTest {

 privateString a ="abc";

 privateintb =123;

 publicReturnTwoget() {

  ReturnTwort =newReturnTwo(this.a,this.b);

  returnrt;

 }

 publicstaticvoidmain(String[] args) {

  Test test =newTest();

  ReturnTwort = test.get();

  System.out.println(rt.first);

  System.out.println(rt.second);

 }

}
