下列语句输出结果为 。public class A{public static void main(String[]args){byte b=0xa;System.out.println(b);}}() A.0xaB.aC.1D.10

根据下面的代码,可以确定类A与类B之间存在()关系。publicclassA{privateBtheB;publicvoidaMethod(){theB.doSomthing();}} A、关联B、泛化C、实现D、包含

23、假定类A已经定义,对于以A为基类的单一继承类B,以下定义中正确的是:()A.class B:public A{//...};B.class A:public B{//...};C.class B:public class A{//...};D.class A:class B public{//...};

下面的代码使用了面向对象的什么特性?() public class A{ public void DoSomething(){} } public class B : A{ new public void DoSomething(){ base.DoSomething();} }A.继承性B.多态性C.封装性D.关联性

下列哪些是合法的类定义语句A.public class A {}B.class A extends Exception,I0Exception {}C.public class 1A extends ObjectD.public class String {}

若要使用两个泛型类型来声明一个名为A的类,请使用A.public class A<E> { ... }B.public class A<E, F> { ... }C.public class A(E) { ... }D.public class A(E, F) { ... }
