Java泛型

感觉和c++的模板很类似，这里记录一下基本的认识

public class Test<T> {
    private T obj;
    public Test(T obj){
        this.obj = obj;
    }
    public T getObj(){
        return this.obj;
    }
    public void setObj(T obj){
        this.obj = obj;
    }
    public void showType(){
        System.out.println("the type is:" + obj.getClass().getName());
    }
    public static void main(String[] args) {
        Test<String> test1 = new Test<String>("string");
        test1.showType();
        Test<Integer> test2 = new Test<Integer>(24);
        test2.showType();
    }
    

}
