the singleton instance is only created the first time helper class is loaded. Subsequent calls to getInstance() return the existing instance since it's declared as static.
Java guarantees that static fields are initialized only once, even in a multi-threaded environment.

Maybe it's worth also mentioning the kotlin way (object keyword and companion) and the spring way(@bean with default scope=singleton)
