Java – “return” stop executing the method?
I have written a method as follows:
if (something) { return 1; } the rest of the code
In my opinion, the method returns 1 and then executes the rest of the code Really? Do not return to stop the execution of the code It's not, how do I force a way to stop?

This is the code (as required):
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; }
I run this code twice In each case, I generate a log file In both log files, I see the "set (by button)" statement (directly before returning) But the problem is that I see the "timer of" statement in the second log file If "set (button)" is reached, it cannot be reached How did this happen? I need to mention that "set (by button)" and "timer" don't happen anywhere in my code (they only happen once)

As you can see from the code, I don't have a finally statement
Solution
This is not true. The return statement will stop any of the following code (the only exception is that the return statement is in the try {} block, followed by a finally {} block
if(0==0){ return; } System.out.println("This will not print.");
