public class SomeException { } Class a: public class a { public void doSomething() { } } Class b: public class b extends a { public void doSomething() throws SomeException { } } Which is true about the two classes?()
Given:10. interface Data { public void load(); }11. abstract class Info { public abstract void load(); }Which class correctly uses the Data interface and Info class?()()
在Java语言中,如果你有下面的类定义: Abstract class Shape{ Abstract void draw(); } class Square extendeds Shape{} 如果你试图编译上面的代码会发生()。
public abstract class Shape { int x; int y; public abstract void draw(); public void setAnchor(int x, int y) { this.x = x; this.y = y; } } and a class Circle that extends and fully implements the Shape class. Which is correct?()
Given: 10.interface Data { public void load(); } 11.abstract class Info { public abstract void load(); } Which class correctly uses the Data interface and Info class?()
现有: interface Data {public void load();} abstract class Info {public abstract void load();} 下列类定义中正确使用Data和Info的是哪项?()
package foo; public class Outer { public static class Inner { } } Which statement is true?()
abstract class abstrctIt { abstract float getFloat (); } public class AbstractTest extends AbstractIt { private float f1= 1.0f; private float getFloat () {return f1;} } What is the result?()
1. interface I { void go(); } 2. 3. abstract class A implements I { } 4. 5. class C extends A { 6. void go(){ } 7. } 结果是什么?()
package foo; public class Outer ( public static class Inner ( ) ) Which statement is true?()
在Java语言中,如果你有下面的类定义: abstract class Shape { abstract void draw(); } Class Square extends Shape {} 如果你试图编译上面的代码会发生()。
interface Data { public void load(); } abstract class Info { public abstract void load(); } Which class correctly uses the Data interface and Info class?()
abstract class abstrctIt { abstract float getFloat (); } public class AbstractTest extends AbstractIt { private float f1= 1.0f; private float getFloat () {return f1;} } What is the result? ()
现有: interface I { void go(); } abstract class A implements I { } class C extends A { void go(){ } } 结果是什么?()
1. abstract class AbstractIt { 2. abstract float getFloat(); 3. } 4. public class AbstractTest extends AbstractIt { 5. private float f1 = 1.0f; 6. private float getFloat() { return f1; } 7. } What is the result?()
下面程序运行的结果是public abstract class A{public A(){Console.WriteLine('A');}public virtual void Fun(){Console.WriteLine(A.Fun());}}public class B : A{public B(){Console.WriteLine('B');}public new void Fun(){Console.WriteLine(B.Fun());}}
给定以下代码interface I { void f(); } abstract class C implements I {}下列哪行代码可以编译成功。
接口(interface)是指只含有公有抽象方法(public abstract method)的类。这些方法必须在()中被实现。
下列接口中标注的(A,B,C,D)中,哪两个是错误的? interface Takecare { protected void speakHello(); //A public abstract static void cry(); //B int f(); //C abstract float g(); //D }
已知定义public class Employee public class Manager extends Employee public class Contr已知定义public class Employee public class Manager extends Employee public class Contractor extends Employee Employee e=new Employee()
下面这段代码编译和运行时会发生什么情况()。 abstract class MineBase { abstract void amethod(); static int i; } public class Mine extends MineBase { public static void main(String[] args) { int[ ] ar = new int[5]; for(int i=0; i < ar.length; i++) System.out.println(ar[i]); } }
对于类定义:class A{public:virtual void func1(){}void func2(){}};class B:public A{public:
14、关于以下C代码的说法正确的是 public abstract class Animal { public abstract void Eat(); } public class Tiger : Animal { public override void Eat() { Console.WriteLine("老虎吃..."); } } public class Tigress : Tiger { static void Main() { Tigress tiger = new Tigress(); tiger.Eat(); } }
16、下列()选项替换程序中的【代码】会导致编译错误。 abstract class AAA { abstract protected int getNumber(); } class BBB extends AAA { 【代码】 }
