unless class private or part of java api, don't see using static advantageous part of oop. the time see using static being useful when need object incrementer every time create new object of same type. for example: public class duck { static int duckcount = 0; private string name; public duck(string name) { this.name = name; duckcount++; } } public class ducktesting { public static void main(string[] args) { system.out.println(duck.duckcount); duck 1 = new duck("barbie"); system.out.println(duck.duckcount); duck 2 = new duck("ken"); system.out.println(duck.duckcount); } } output: 0 1 2 update: useful answers found in java: when use static methods/variable so here's little exemple : let's need create people profiles, we'll make class named profile , need every profile have id public class profile{ int id; string name; public profile(string name,int id) {this.name=name; ...
