java static final泛型类对象
class TestClass<T> {
public T t;
public void setT(T t) {
this.t = t;
}
public T getT() {
return t;
}
}
public class StaticObj {
public static final TestClass<Integer> tc = new TestClass<Integer>();
public static void main(String[] args) {
tc.setT(new Integer(101));
System.out.println("tc.t: "+tc.getT()+"
");
tc.setT(new Integer(102));
System.out.println("tc.t: "+tc.getT()+"
");
tc.setT(new Integer(103));
System.out.println("tc.t: "+tc.getT()+"
");
//tc = new TestClass<Integer>(); //cannot assign new value to a final object
}
}
运行结果：
tc.t: 101
tc.t: 102
tc.t: 103
