Java的泛型之简单讲解

-------------------------泛型就是变量类型的参数化------------------

写一个简单的泛型的例子

class FanXing<T>

{

private T a;

public T getT()

{

return a;

}

public void setT(T a)

{

this.a = a;

}

public static void main()

{

FanXing<String> fan1 = new FanXing<String>();

fan1.set("hello,world");

String str1 = fan1.get();

FanXing<Integer> fan2 = new FanXing<Integet>();

fan2.set(1);

int int1 = fan2.get();

System.out.println(str1);

System.out.println(int1);

}

}
