Complete the following program

Write a program called VariableNameChecker that checks the properness of a given variable name. More specifically, your program should specify whether a user-entered variable name is:

• illegal
• legal, but uses poor style
• good.

There are different opinions as to what constitutes good style for a variable name. For this program, check for good style using these rules:

• Only use letters and digits.
• Use a lowercase letter for the first character.

You don’t need to check for an uppercase letter for the first letter in the second word, third word, etc.

Remember that it is illegal to have spaces in a java variable name and you cannot start a variable name with a numeric digit.

Sample session output

Legal, but uses poor style.
Enter a variable name (q to quit): q
