What is the equivalent keyword for extern in java?

Question

I have one public static variable in one file and how can I export the same variable to other files?

For ex:-

file1.java

public final static int buf = 256;

file2.java

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

Answer 1

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)

Answer 2

File1.buf

correct definition: public static final int BUF = 256;

so you would call it in other class:

File1.BUF;
