JAVA多线程 编程题两个案例,不会写,求大神写出代码,万分感谢,多线程还没学。
/*
class A extends Thread
{
public void run()
{
try
{
Thread.sleep(1000);
}catch(Exception e)
{
System.out.println("A ERROR!");
}
System.out.println("AAAA");
}
}
class B extends Thread
{
public void run()
{
try
{
Thread.sleep(2000);
}catch(Exception e)
{
System.out.println("B ERROR!");
}
System.out.println("BBBB");
}
}
class C extends Thread
{
public void run()
{
try
{
Thread.sleep(3000);
}catch(Exception e)
{
System.out.println("C ERROR!");
}
System.out.println("CCCC");
}
}
public class Test_1
{
public static void main(String[] args)
{
A a = new A();
B b = new B();
C c = new C();
a.start();
b.start();
c.start();
}
}*/
public class Test_1
{
public static void main(String[] args)
{
A a = new A();
B b = new B();
C c = new C();
Thread ta = new Thread(a);
Thread tb = new Thread(b);
Thread tc = new Thread(c);
ta.start();
tb.start();
tc.start();
}
}
class A implements Runnable
{
public void run()
{
try
{
Thread.sleep(1000);
}catch(Exception e)
{
System.out.println("A ERROR!");
}
System.out.println("AAAA");
}
}
class B implements Runnable
{
public void run()
{
try
{
Thread.sleep(2000);
}catch(Exception e)
{
System.out.println("B ERROR!");
}
System.out.println("BBBB");
}
}
class C implements Runnable
{
public void run()
{
try
{
Thread.sleep(3000);
}catch(Exception e)
{
System.out.println("C ERROR!");
}
System.out.println("CCCC");
}
}
案例一的两种方法已经写好;现在有事,晚态宴弊上再把案例二代码写一下,应该没关系吧帆族祥乎!
抱歉,是一个线程类,我看错了,晚上重发一下代码!
