Java - 计算负载系数

Question

我正在尝试计算我的Hashtable的加载因子并打印出结果。但是，当我运行它时，加载因子等于2.这是我的地图的大小 - 所以我的方法loadFactor不是很有效。有什么明显的东西我不见了吗？ （我对Java很新）

    - (BOOL) warningAlert:(NSString* )messageText informText:(NSString*)informText {
  // Displays a fading, then self-dismissing view within the top level window

  __block NSInteger alertReturn = 0; // __block, so it can be accessed by the completion blocks

  // Define the alert
  NSAlert* __block generalAlert = [[NSAlert alloc] init];
  [generalAlert addButtonWithTitle:@"Continue?"];
  [generalAlert addButtonWithTitle:@"Cancel"];
  [generalAlert setMessageText:messageText];
  [generalAlert setInformativeText:informText];
  [generalAlert setAlertStyle:NSAlertStyleWarning];

  // Animate the fading box, with the passed completion criteria alertReturn = NSModalResponseStop
  [NSAnimationContext beginGrouping];
  // Animate alpha fade
  [[NSAnimationContext currentContext] setDuration:5.0];
  [[NSAnimationContext currentContext] setCompletionHandler:^{
    // Dismiss the alert
    NSWindow *window = [NSApp mainWindow];
    [[window attachedSheet] close];
    NSLog(@"Closed the Sheet");
    alertReturn = NSModalResponseStop;
  }];
  [[generalAlert.window animator] setAlphaValue:0.0];
  [NSAnimationContext endGrouping];

  // Begin the alert.
  // For the completion criteria, speed up the animation to it's conclusion, but not before we return to the calling method
  [generalAlert beginSheetModalForWindow:self.mySwiftCentral.sxWindowController.window completionHandler:^(NSInteger result) {
    [NSAnimationContext beginGrouping];
    [[NSAnimationContext currentContext] setDuration:0.01];
    [[generalAlert.window animator] setAlphaValue:0.0];
    [NSAnimationContext endGrouping];
    alertReturn = result;
    NSLog(@"Success, alertReturn = %ld",(long)alertReturn);
  }];

  // Create a NSModalSession using the global Application Instance variable NSApp
  NSModalSession session = [NSApp beginModalSessionForWindow:
                            self.mywindow];
  alertReturn = NSModalResponseContinue;

  // Loop here until the user responds or the animation completes, either of which will modify alertReturn and break out of the loop
  // Without the NSModalSession, this loop would block user button actions or animation timeout.
  for (;;) {
    [NSApp runModalSession:session];
    if (alertReturn != NSModalResponseContinue)
      break;
    // Break on timeout here
  }
  [NSApp endModalSession:session];

  NSLog(@"Alert Return = %ld",(long)alertReturn);
  if (alertReturn == NSAlertFirstButtonReturn ||
      alertReturn == NSModalResponseStop) {
    return YES;
  }
  else return NO;

}
