Here's some code to limit the number of instances that can be created for a particular class. The limit has been set to 10 in this example but can be anything you want: import java.io.*; class A { int a; public int getField() { return a; } static final int limit = 10; static int count = 0; public static int getCount() { return count; } public static A Create(int a) { if (count { A instance = new A(a); count++; return instance; } else { System.out.println(There are already  + limit +  instances of A in existence); return null; } } private A(int a) { this.a = a; } } class Test { public static void main(String[] args) { A[] aa = new A[11]; for(int i = 0; i { aa[i] = A.Create(i); // try to create 11 A objects } System.out.println(A.getCount()); // 10 } }
