Language Java. Define a class representing physical elements (like hydrogen, helium, lithium, etc.). Elements have a name, a symbol, an integer atomic number, and an atomic weight (which may be fractional). Your class should have a constructor that sets all the properties. In your test program, create and print several real elements using the real values for their properties. For example, for the element hydrogen your program might print something like this: “Hydrogen (H) - Atomic No 1 - Atomic Weight 1.008”. You are free to choose a different output format, as long as all four pieces of information are presented.
