[color=red][size=x-large]两种定义方式[/size][/color]
定义方式一:
class TestThread extends Thread{
public void run(){
........................
}
}
Thread t = new TestThread();
t.run()
//或者
t.start();
定义方式二:
Thread t = new Runnable(
public void run(
..........
){}
);
t.run()
//或者
t.start();

Runnable是Thread的接口,在大多数情况下“推荐用接口的方式”生成线程,因为接口可以实现多继承,况且Runnable只有一个run方法,很适合继承。
在使用Thread的时候只需要new一个实例出来,调用start()方法即可以启动一个线程。
Thread Test = new Thread();
Test.start();
在使用Runnable的时候需要先new一个继承Runnable的实例,之后用子类Thread调用。
Test impelements Runnable
Test t = new Test();
Thread test = new Thread(t);
在某个题目里,需要分别打印出a与b各10次,并且每打印一次a睡1秒,打印一次b睡2秒。
可以在run方法外面定义String word与int time
之后用
Thread t1 = new Thread();
Thread t2 = new Thread();
t1.word = "a"
t1.time = 1000
t2.Word = "b"
t2.time = 2000
t1.start();
t2.start();
----Runnable的代码
class T implements Runnable{
String s = "";
int time = 0;
public void run (){
for (int i=0;i<10;i++) {
try {
Thread.sleep(time);
} catch (InterruptedException e) {
Thread.interrupted();
}
System.out.println(s);
}
}
}
public class Test {
public static void main(String[] args) {
T t1 = new T();
T t2 = new T();
t1.s = "a";
t1.time = 100;
t2.s = "b";
t2.time = 200;
Thread a = new Thread(t1);
a.start();
Thread b = new Thread(t2);
b.start();
}
}
