There are several ways to handle exceptions in Java multi-threading:<\/p>\n

    \n
  1. Handle exceptions within the run method by using a try-catch statement, and then handle the exceptions in the catch block.<\/li>\n<\/ol>\n
    public<\/span> class<\/span> MyRunnable<\/span> implements<\/span> Runnable<\/span> {\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> run<\/span>()<\/span> {\r\n        try<\/span> {\r\n            \/\/ \u6267\u884c\u7ebf\u7a0b\u4efb\u52a1<\/span>\r\n        } catch<\/span> (Exception e) {\r\n            \/\/ \u5904\u7406\u5f02\u5e38<\/span>\r\n        }\r\n    }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. When submitting a task using the submit method of ExecutorService, you can use the get method of the Future object to retrieve the execution result and catch exceptions when calling the get method.<\/li>\n<\/ol>\n
      ExecutorService<\/span> executorService<\/span> =<\/span> Executors.newFixedThreadPool(10<\/span>);\r\nFuture<?> future = executorService.submit(new<\/span> MyRunnable<\/span>());\r\ntry<\/span> {\r\n    future.get();\r\n} catch<\/span> (Exception e) {\r\n    \/\/ \u5904\u7406\u5f02\u5e38<\/span>\r\n}\r\n<\/code><\/pre>\n
        \n
      1. Use the UncaughtExceptionHandler interface to handle uncaught exceptions. You can set a default handler for uncaught exceptions using the setDefaultUncaughtExceptionHandler method in the Thread class, or set a specific handler for a thread using the setUncaughtExceptionHandler method in the Thread class.<\/li>\n<\/ol>\n
        Thread.setDefaultUncaughtExceptionHandler(new<\/span> Thread<\/span>.UncaughtExceptionHandler() {\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> uncaughtException<\/span>(Thread t, Throwable e)<\/span> {\r\n        \/\/ \u5904\u7406\u672a\u6355\u83b7\u5f02\u5e38<\/span>\r\n    }\r\n});\r\n<\/code><\/pre>\n
          \n
        1. Customize an uncaught exception handler using the Thread.UncaughtExceptionHandler interface, and catch exceptions in the run method using a try-catch statement, then throw the exception through the uncaughtException method of the UncaughtExceptionHandler interface.<\/li>\n<\/ol>\n
          public<\/span> class<\/span> MyRunnable<\/span> implements<\/span> Runnable<\/span> {\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> run<\/span>()<\/span> {\r\n        try<\/span> {\r\n            \/\/ \u6267\u884c\u7ebf\u7a0b\u4efb\u52a1<\/span>\r\n        } catch<\/span> (Exception e) {\r\n            Thread.currentThread().getUncaughtExceptionHandler().uncaughtException(Thread.currentThread(), e);\r\n        }\r\n    }\r\n}\r\n\r\nThread.UncaughtExceptionHandler<\/span> handler<\/span> =<\/span> new<\/span> Thread<\/span>.UncaughtExceptionHandler() {\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> uncaughtException<\/span>(Thread t, Throwable e)<\/span> {\r\n        \/\/ \u5904\u7406\u672a\u6355\u83b7\u5f02\u5e38<\/span>\r\n    }\r\n};\r\nThread<\/span> thread<\/span> =<\/span> new<\/span> Thread<\/span>(new<\/span> MyRunnable<\/span>());\r\nthread.setUncaughtExceptionHandler(handler);\r\nthread.start();\r\n<\/code><\/pre>\n
          You can choose a suitable processing method based on specific needs, regardless of which method is used.<\/p>\n","protected":false},"excerpt":{"rendered":"
