我在執(zhí)行軟件時(shí)遇到以下異常：Exception in thread "main" java.lang.IllegalArgumentException: Delay must be to 0 to 60,000ms    at java.awt.Robot.checkDelayArgument(Robot.java:544)    at java.awt.Robot.delay(Robot.java:534)    at com.company.Main.main(Main.java:10)令我驚訝的是，有一個(gè)睡眠時(shí)間限制，并且標(biāo)準(zhǔn)庫(kù)異常消息有錯(cuò)誤的語(yǔ)法/拼寫(xiě)錯(cuò)誤（to 0 to？）。檢查該方法的源代碼后delay()，我注意到它限制了等待時(shí)間，如異常所述：/** * Sleeps for the specified time. * To catch any <code>InterruptedException</code>s that occur, * <code>Thread.sleep()</code> may be used instead. * @param   ms      time to sleep in milliseconds * @throws  IllegalArgumentException if <code>ms</code> is not between 0 and 60,000 milliseconds inclusive * @see     java.lang.Thread#sleep */public synchronized void delay(int ms) {    checkDelayArgument(ms);    try {        Thread.sleep(ms);    } catch(InterruptedException ite) {        ite.printStackTrace();    }}private static final int MAX_DELAY = 60000;private void checkDelayArgument(int ms) {    if (ms < 0 || ms > MAX_DELAY) {        throw new IllegalArgumentException("Delay must be to 0 to 60,000ms");    }}為什么要這樣做？這似乎是糟糕的 API 設(shè)計(jì)。InterruptedException除了為你捕獲多余的檢查異常并同步調(diào)用之外，它還有什么目的？
