.equals() NullPointer

Error happens here.

Code:

if(AString.equals("white"))

before this , I already do :

Code:

setAString("white");

, I have already tried to use a Helper method than return true if its equal or false if its not , but still same issue....any ideas?

 

Are you sure its .equals()? I think it's probably AString being the NPE.

 

AString is "white" (I do it before this if takes place (I tried before to check while it was null but same thing))

 

So, you're doing

Code:java

String AString = "white";

? That would be wrong. You're checking if the String equals a String.. It's pointless.. You shouldn't do that, you should check if (if it's an args) args[?].equalsIgnoreCase(AString);

 

Nope , I am doing :
- A declaration on another class
-on onEnable I call a method thats called variableInit(Sets default values for varjiables)
I have in variableinit , anotherclass.setAString("white")
-A scheduler runs doing some checks I can say , but stucks on anotherclass.getAString().equals("white")
and no , I am not setting before AString to a value

 

Zarkopafilis Ahhh, OK, I'm not sure what the problem is then.

 

Aw my god, how am I supposed to troubleshoot this thing...?

 

Zarkopafilis You could try and print out the messages, and see if one of them returns null?

 

Still after the anotherclass.setAString("white") it returns back null :S now what?

 

Maybe try fix it. Make it public, make it static, or whatever you need to do. I'm not sure.

 

As far as setter is public , I dont need to make it public , and static???why???Its value will be changing....

 

Zarkopafilis I wasn't telling you to change it to static.. I was just suggesting in the case of it needing to be. I'm not entirely sure what the problem is at the moment.. I don't think I'm going to be much help after this, so just wait till someone more experienced come along and see this.

 

Zarkopafilis if the string from the other class is public, you can use otherclass.AString = "white"; because I think there is something wrong in your setAString("blablabla");
Also are you referencing in a static manner, or are you using an instance of that class?

 

Sure helped, also I looked at a trick , instead of otherclass.AString.equals("white") , I make a string called white , give it "white" value and then , I can do white.equals(otherclass.AString)

 

Zarkopafilis
You don't need to create a variable to do that.

Code:

if("white".equals(otherclass.AString)) ...

But it would be best to figure out why your AString (which is badly named by the way) is null in the first place when it should return a value.

 

Okay ..
