Java does not support macros. IIRC, the language designers felt that macros and the resultant preparser was an unnecessary and undesirable complication.

Use a function instead:

public int readInt(Scanner inp) {
    return inp.nextint();
    }

Elsewhere:

Scanner input=new Scanner(System.in);

...


int a=readInt(input);

Note also, that I create the scanner once and reuse it.
