Initialize JLabel array and fill

[Soulpole]

Hey guys,

I am trying to create an array of JLabel objects and fill them with one line of code.
However when I try this it is not seeing it as an array but rather a JLabel object.

Here is my code:

JLabel JLabel[] = {new JLabel("Label 1"), new JLabel("Label 2"), new JLabel("Label 3"), new JLabel("Label 4")};

symbol  : method getLength()
location: class javax.swing.JLabel[]
	  for (int i = 0; i < JLabel.getLength(); i++) {
	                            ^
1 error

Thanks in advance,
Nate

Follow coding conventions. Variable (and also method) names start with a lowercase letter.

Also, never use an existing class name as an identifier. The compiler is interpreting JLabel as the class name javax.swing.JLabel -- not the array variable you declared with the same name.

And in future, COPY error messages that you need help with. This certainly isn't the error you got.

symbol  : method getLength()
location: class javax.swing.JLabel[]

edit: Additionally, arrays don't have a getLength() method. They have a length member. You need to go through some tutorials, programming by guesswork is never satisfying.

Thanks for the response,
I did change my variable name to a more appropriate variable name. As for the error message you were correct again. When I used myvar.length it let me compile. I am confused however; I was referencing Oracle's website (API's) java.util.Array and I found a getLength() modifier. That is why I was trying to use myvar.getLength(); I thought that returned my integer.

My question is: Is there any API that I can see the "array.length" and like attributes?

Thanks again,
Nate

Read the specification:
