现有: class Thread2 implements Runnable { void run() { System.out.print("go "); } public static void main(String [] args) { Thread2 t2 = new Thread2(); Thread t = new Thread(t2); t.start(); } } 结果为:()
关于Runnable接口,正确的说法是()。
在JAVA编程中,实现Runnable接口时必须实现的方法是()。
Which method must be defined by a class implementing the java.lang.Runnable interface? ()
public class Threads3 implements Runnable { public void run() { System.out.print(”running”); } public static void main(String[] args) { Thread t = new Thread(new Threads3()); t.run(); t.run(); t.start(); } } What is the result?()
class Thread2 implements Runnable { void run() { System.out.print("go "); } public static void main(String [] args) { Thread2 t2 = new Thread2(); Thread t = new Thread(t2); t.start(); } } 结果为:()
class ThreadBoth extends Thread implements Runnable { public void run(){ System.out.print("hi "); } public static void main(String [] args){ Thread t1 = new ThreadBoth(); Thread t2 = new Thread(t1); t1.run(); t2.run(); } } 结果为:()
public class Threads5 { public static void main (String[] args) { new Thread(new Runnable() { public void run() { System.out.print(”bar”); } }).start(); } } What is the result?()
利用Runnable接口实现线程必须复写run()方法,这个run()方法是由哪一个方法调用的()。
现有: class Thread2 implements Runnable { void run() { System.out.print("go "); } public static void main(String [] args) { Thread2 t2 = new Thread2(); Thread t = new Thread(t2); t.start(); } } 结果为:()
2. public class Foo implements Runnable ( 3. public void run (Thread t) { 4. system.out.printIn(“Running.”); 5. } 6. public static void main (String[] args) { 7. new thread (new Foo()).start(); 8. ) 9. ) What is the result?()
Runnable接口中的抽象方法是()。
public class Foo implements Runnable ( public void run (Thread t) { system.out.printIn(“Running.”); } public static void main (String args) { new thread (new Foo()).start(); } ) What is the result?()
public class Foo implements Runnable ( public void run (Thread t) { system.out.printIn(“Running.”); } public static void main (String[] args) { new thread (new Foo()).start(); } ) What is the result?()
public class Foo implements Runnable ( public void run (Thread t) { system.out.printIn(“Running.”); } public static void main (String args) { new thread (new Foo()).start(); } ) What is the result?()
线程有 新建( New )、就绪(Runnable)、运行(Running)、阻塞( Blocked )和死亡( Dead )5种状态,哪些情况会导致线程进入阻塞状态?
以下关于Runnable接口的描述错误的是( )
通过继承Thread类、Runnable类创建线程。 ( )
(1702-89)Thread类实现了Runnable接口,继承Object类
新建线程时,不管是继承Thread类还是实现Runnable接口,都需要重写其中的run()方法
Runnable接口继承自Thread类
5、Runnable接口定义了如下哪些方法?()
【单选题】实现线程可以继承下面那个类别() A. Thread B. Runnable C. Object D. Math
下列能够正确创建线程的方法是()。Ⅰ.继承java.lang.Thread类,并重写run()方法Ⅱ.继承java.lang.Runnable类,并重写start()方法Ⅲ.实现java.lang.Thread接口,并实现run()方法Ⅳ.实现java.lang.Runnable接口,并实现run()方法
