假设我们有以下两个Runnable:
class R1 implements Runnable {
public void run() { … }
…
}
class R2 implements Runnable {
public void run() { … }
…
}
那么这有什么区别:
public static void main() {
R1 r1 = new R1();
R2 r2 = new R2();
r1.run();
r2.run();
}
还有这个:
public static void main() {
R1 r1 = new R1();
R2 r2 = new R2();
Thread t1 = new Thread(r1);
Thread t2 = new Thread(r2);
t1.start();
t2.start();
}
