I have porblem with homework..someone who know how to write it pleas help



Write a class that can be created only in a single instance and only by some specific method.

For example this should work:

SingleInstance pInst = SingleInstance.getInstance();
pInst.someMethod();

And this shouldn't:

SingleInstance oneInstance = new SingleInstance();
oneInstance.someMethod();

The second call to getInstance() method should return the pointer to the already existing object and do not create a new one.

Hints: private, public, static

have you tried any code yet. People around here don't do homework for people. Post your code, then people will help you.

We aren't a home work service.
