java中如何靠著throw拋出一個(gè)異常來停止線程
把上面的程序return,變成自己通過throw主動(dòng)拋出異常,結(jié)果是一樣的。
例:1.5.1_1-本章源碼
馬克- to-win:馬克 java社區(qū):防盜版實(shí)名手機(jī)尾號(hào): 73203。
class MyThreadMark_to_win extends Thread{
private boolean stop;
public void run() {
for (int i = 0; i < 100; i++) {
if (stop) {
System.out.println("退出了");
throw new ArithmeticException("divide by 0");
}
try {
Thread.sleep(200);
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("i = " + i);
}
}
public void setStop(boolean stop) {
this.stop = stop;
}
}
public class Test {
public static void main(String[] args) {
MyThreadMark_to_win mt = new MyThreadMark_to_win();
mt.start();
try {
Thread.sleep(300);
} catch (Exception e) {
}
mt.setStop(true);
}
}
輸出結(jié)果:
i = 0
Exception in thread "Thread-0" java.lang.ArithmeticException: divide by 0
at MyThreadMark_to_win.run(Test.java:7)
i = 1
退出了
