是否“返回"?停止执行方法?

2022-01-19 00:00:00 return java

我用以下方式编写了一个方法:

I have programmed a method in the following way:

if (something) {
   return 1;
}
the rest of the code

在我看来，该方法返回 1，然后执行 其余代码.这可能是事实吗?return 不会停止代码的执行.不是，如何强制方法停止?

It seems to me that the method returns 1 and then execute the rest of the code. Can it be the truth? Doesn't return stops the execution of the code. It it is not, how can I force a method to stop?

这是代码(根据要求):

Here is the code (as requested):

    for (int i=availableTime; i>0; i=i-1) {
            final int sec = i;
            SwingUtilities.invokeLater(new Runnable() {
                public void run() {
                    String lbl = "<html>";
                    lbl += "</html>";
                    timeLeftLabel.setText(lbl);
            }
            });
            try {Thread.sleep(1000);} catch (InterruptedException e) {}
            parameterFromClientsListener = clientsListener.getValue(userName,parameterToGet);
            if (!parameterFromClientsListener.equals("null")) {
                output = parameterFromClientsListener;
                game.log.fine(userName + " set (by button) " + parameterToGet + " to be equal to " + output + " . [IMPORTANT]");
                return output;
            }
    }

    game.log.fine("The partner selection phase is expired.");
    // This code is executed if the Submit button was not pressed and the time run out.
    if (parameterToGet.equals("partner")) {
        tellMyChoice(parameterToGet, this.partnerFromForm, "timer of" + field);
        output = this.partnerFromForm;
    }
    game.log.fine(parameterToGet + " was submitted by timer (not by OK button).");
    } else {
    output = parameterFromClientsListener;
    }
    game.log.fine(userName + " set (by timer)" + parameterToGet + " to be equal to " + output + " . [IMPORTANT]");
    return output;
}

我运行此代码两次.在每种情况下，我都会生成一个日志文件.在两个日志文件中，我都看到设置(按按钮)"语句(直接在 return 之前).但问题是在第二个日志文件中我确实看到了timer of"语句.如果达到设置(按按钮)"，则不应达到.怎么可能?我需要提一下，设置(按按钮)"和计时器"不会出现在我的代码中的其他任何地方(它们只出现一次).

I run this code two times. In every case I generate a log-file. In both log files I see "set (by button)" statement (which is straight before the return). But the problem is that in the second log file I do see "timer of" statement. Which should not be reached if the "set (by button)" is reached. How can it be? I need to mention that "set (by button)" and "timer of" do not occur anywhere else in my code (they occur only once).

从代码中可以看出，我没有 finally 语句.

As you can see from the code I do not have the finally statement.

推荐答案

这不是真的，return 语句会停止后面的任何代码.(唯一的例外是 return 语句位于 try{} 块中，该块之后有一个 finally{} 块.

This is not true, the return statement will stop any following code. (With the only exception being that the return statement is in a try{} block that has a finally{} block afterwards.

    if(0==0){
       return;
    }
    System.out.println("This will not print.");
