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)
