Java 泛型T的简单使用（一）

public class demo {

public static void main(String[] args) {
demo d = new demo();
Any<Integer> any1 = d.new Any<Integer>();
any1.write(1);

Any<Integer> any2 = d.new Any<Integer>();
any2.write(2);

System.out.println("" + containts(any1,any2));

}

public static <T> String containts(Any<T> t1,Any<T> t2){
if(t1.read().equals(t2.read())){
return "1";
}else{
return "2";
}
}

class Any<T> {
private T t;

public T read() {
return t;
}

public void write(T tt) {
t = tt;
}

public Any() {
}
}
}
