Java – there are only five instances of classes

• Java

I want only five instances of classes throughout the application lifecycle How can I do this? If possible, please provide sample code

Solution

Since singles should use enumeration (see "valid Java"):

public enum FiveInstance {

  INSTANCE1,INSTANCE2,INSTANCE3,INSTANCE4,INSTANCE5;

  public void anyMethod() {}

}
