Java newbie - cannot find symbol - variable

let's say I have : public static int MIN = 0; in a class.

and I am trying to use this constant in another class with main : myVar = MIN;

why am I getting cannot find symbol - variable MIN error? both classes are public and so is the constant MIN.

any help would be appreciated. thank you fellow coders

e; thank you guys, it worked!

You need to type myVar = ClassName; instead of just myVar = MIN;. you also need to import the class import ClassName.*; or import ClassName;. If you import it staticly: import static ClassName; you can do myVar = MIN;;

You need to specify the name of class that has the attribute. For do that, follow this syntax:

ClassName.attribute;

In this case the variable is static, but if you are using a class with non-static members you first have to create a object of the class and then call it, for example:

MyClass sampleClass = new MyClass();

sampleClass.attribute;

Then you need to access the value with ClassName.MIN, where ClassName is the name of the class which includes MIN.

You should search on this simple thing and you would have got a lot of links,anyway try this, the where you defined 

public static int MIN = 0;

try like this

myVar = that_class_name.MIN

Hope it will work.

In order to use a class constant like MIN from a class A, you would need to

import static A.MIN;

or you could use

int myVar = A.MIN;
