"const" is a reserved word, but it has no function in Java. You cannot use it.
The most likely reason why it's there is because it was inherited from C++. In the first version of Java, the language designers decided to reserve the word "const", with the idea of maybe implementing it in a later version of Java. But to date, it hasn't been implemented.
