下列程序创建了一个线程并运行，请在下画线处填入正确代码。 public class Try extends Thread public static void main(String args[]) Thread t=new Try(); ______; public void run() System.out.printin("Try!");
举一反三
- class X implements Runnable{public static void main(String args[]){/* Missing code? */}public void run() {}}哪一行代码适合启动线程？ A: Thread t = new Thread(X); B: Thread t = new Thread(X);t.start(); C: X run = new X();Thread t = new Thread(run);t.start(); D: Thread t = new Thread();x.run();
- 阅读下面的程序，分析代码是否能编译通过。如果能编译通过，请列出运行的结果;如果不能编译通过，请说明原因。class RunHandler {public void run() {System.out.println("run");}}public class Read01 {public static void main(String [] args) {Thread t = new Thread(new RunHandler( ));t.start( );}}
- class MyException extends (1) { } public class Demo { public static void main(String[] args) { try { show(); } catch ( (2) e) { e.printStackTrace(); } } public static void show() (3) MyException { throw new MyException(); } 以上程序,创建了一个自定义异常(编译异常),请补全空白处代码
- Given: 1. public class Foo implements Runnable { 2. public void run (Thread t) { 3. System.out.println("Running."); 4. } 5. public static void main (String[] args) { 6. new Thread (new Foo()).start(); 7. } 8. } What is the result?
- 下列程序执行的结果是（ ）。 public class X7_1_6 { public static void main(String[] args) { try{ return; } finally{ System.out.println("Finally"); } } }
