问题描述
如何在线程中使用异常?
解决方案
此示例展示了如何在处理线程时处理异常。
class MyThread extends Thread{
public void run(){
System.out.println("Throwing in " +"MyThread");
throw new RuntimeException();
}
}
public class Main {
public static void main(String[] args) {
MyThread t = new MyThread();
t.start();
try {
Thread.sleep(1000);
} catch (Exception x) {
System.out.println("Caught it" + x);
}
System.out.println("Exiting main");
}
}
结果
上述代码示例将产生以下结果。
