Stupid if-then-else statements. (this should be basic)

[BlueLight]

Okay, so i've always had a problem with If statements and i don't know why. Anyways I need to fix this before I can't get something important to work.

I've got this section of code.

Code: Select All Code

public void actionPerformed(ActionEvent event) {
      // TODO Auto-generated method stub
      String state = event.getActionCommand();
      Log.Logging(this.getClass().getName(), ""+state);
      if(newGameString == state){Center.texyTextAdderCenter(state, false, true);}
      if(saveGameString == state){Center.texyTextAdderCenter(state, false, true);}
      if(loadGameString == state){Center.texyTextAdderCenter(state, false, true);}
      if(optionsString == state){Center.texyTextAdderCenter(state, false, true);}
      if(quitString == state){Center.texyTextAdderCenter(state, false, true);}
      else {
         Center.texyTextAdderCenter("What the F did you do? This is a bug and needs to be reported!... Like now.", false, true);
         Center.texyTextAdderCenter("I need you to go to LoK forums or my blog and post this third line in a comment or something that I can read.", false, true);
         Center.texyTextAdderCenter(event+"", false, true);
         Center.texyTextAdderCenter("Again, how the hell did you do this? My if statement logic leaves no room for error so how the hell did you trigger the else statement?", false, true);
      }
   }
}

Here's the problem, when ever my action listener fires (the thing above.) it will compare the values just fine, but, the else statement will also fire. I'm getting results like

Code: Select All Code

New Game
What the F did you do? This is a bug and needs to be reported!... Like now.
I need you to go to LoK forums or my blog and post this third line in a comment or something that I can read.
java.awt.event.ActionEvent[ACTION_PERFORMED,cmd=New Game,when=1334556942200,modifiers=Button1] on javax.swing.JMenuItem[,1,3,85x21,invalid,alignmentX=0.0,alignmentY=0.0,border=javax.swing.plaf.metal.MetalBorders$MenuItemBorder@360be0,flags=264,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResource[top=2,left=2,bottom=2,right=2],paintBorder=true,paintFocus=false,pressedIcon=,rolloverEnabled=false,rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=New Game]
Again, how the hell did you do this? My if statement logic leaves no room for error so how the hell did you trigger the else statement?

See Attachment. Looks to me like you have an extra } floating, which is probably messing up your logic.

WHY MUST YOU BE TALKING TO MY DAD, GAH!!!!!
He's always telling me that i should comment after a bracket so people know what's open and what's closed.

So the third bracket is to state the class ends. classes are objects or items that you can change and modify in some way.
So a int is a object and there is in fact a class called integer in the API (primitives are the strangest objects because they have their own class but you don't have to call the class to make them.)
basically that should be there in the main code but you can't see what that is connected to with this example.

Anyways i fixed the problem, this is stupid beyond belief which i'm not shocked to learn, you have put a else in front of the if statements after the first one.

Code: Select All Code

public void actionPerformed(ActionEvent event) {//start actionListener, in GameMenuBar class.
      // TODO Auto-generated method stub
      String state = event.getActionCommand();
      Log.Logging(this.getClass().getName(), ""+state);
      if(newGameString == state){Center.texyTextAdderCenter(state, false, true);}
      else if(saveGameString == state){Center.texyTextAdderCenter(state, false, true);}
      else if(loadGameString == state){Center.texyTextAdderCenter(state, false, true);}
      else if(optionsString == state){Center.texyTextAdderCenter(state, false, true);}
      else if(quitString == state){System.exit(0);}
      else {
         Center.texyTextAdderCenter("What the F did you do? This is a bug and needs to be reported!... Like now.", false, true);
         Center.texyTextAdderCenter("I need you to go to LoK forums or my blog and post this third line in a comment or something that I can read.", false, true);
         Center.texyTextAdderCenter(event+"", false, true);
         Center.texyTextAdderCenter("Again, how the hell did you do this? My if statement logic leaves no room for error so how the hell did you trigger the else statement?", false, true);
      }// end else
   } //end method
}// end class

I also added a few comments.

Sorry but that isn't stupid, it makes so much sense Without the else statement, each if statement is being called in turn regardless of whether the others returned true.

Although you could also put "return;" into each of the curly brace sections after the if statements, that way it would end the function once one returns true

[BlueLight]

You can only put return in to a method that has something to return. This method returns "Void" which is a another way of saying nothing.
Why is everyone commenting on my request for help today? I mean i fixed these at least a week ago.

As for why it's stupid. According to oracle, the if() statements test until one passes the test or you run out of if() statements
