使用setUncaughtExceptionHandler在線程外面捕獲異常

package com.dwz.concurrency.chapter11;
/**
 * Thread的run方法是不能throw出異常的，只能在日志或者console中打印出來
 */
public class ThreadException {
    private final static int A = 10;
    private final static int B = 0;
    
    public static void main(String[] args) {
        Thread t = new Thread(()->{
            try {
                Thread.sleep(5_000);
                int result = A/B;
                System.out.println(result);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        });
        
        //該方法可以在線程外面捕獲到異常
        t.setUncaughtExceptionHandler((thread, e)->{
            System.out.println(e);
            System.out.println(thread);
        });
        t.start();
    }
}

使用了setUncaughtExceptionHandler后會把異常處理交給setUncaughtExceptionHandler，線程里面的異常不再輸出日志信息
