JAVA

How can i make my code increment by 1 (starting from 0, then print 1, then print 2, then print 3...)

I also want the random incrementer to print a new random number (random number, then another random number, then another number....)

these are 4 different files. Can someone tell me what loops to include so my code will print increments?

public interface Incrementable public void increment); public int getValue()
