What is the equivalent keyword for extern in java?

I have one public static variable in one file and how can I export the same variable to ot开发者_如何转开发her files?

For ex:-

file1.java

public final static int buf = 256;

file2.java

How can I access the variable "buf" in this file?

File1.buf. More generally: ClassName.FIELD_NAME. A few notes

• use CAPITAL_LETTERS to name your static final fields (BUF)
• use static final rather than final static (not crucial, but it is a widely accepted style)

File1.buf

correct definition: public static final int BUF = 256;

so you would call it in other class:

File1.BUF;
