CompletableFuture使用

package com.linear.table;

import java.util.concurrent.CompletableFuture;

public class CompletableFutureTest {
public static void main(String[] args) throws InterruptedException, Exception {
    CompletableFuture<String>completableFuture=new CompletableFuture<>();
    new Thread(()->{
        System.out.println("runing...");
        try {
            Thread.sleep(5000);
            // 告诉completableFuture任务已经完成
            completableFuture.complete("ok");
            
            int i=10/0;//制造异常
        } catch (Exception e) {
            System.out.println(e.toString());
            // 告诉completableFuture任务发生异常了
            completableFuture.completeExceptionally(e);
            
        }
        
    }).start();
    /**
     * 如果该线程没有执行完成，处于阻塞状态，不会再执行后面的代码，
     */
    
    String result=completableFuture.get();
    if(result.equals("ok")){
        System.out.println("執行完le ..."+":"+result);
        
    }
}
}

运行结果：
runing...
java.lang.ArithmeticException: / by zero
執行完le ...:ok
