title: How to make a Java Main Menu Loop after using a case
body: <p>I am pretty dang new to Java, but being familiar with some other programming languages, I know the basic lay out of a lot of it. One thing I am struggling with is looping menus, specifically a main menu.</p>
  
  <p>I have tirelessly researched methods of it, but none seem to apply or work to my program. I'm assuming its something silly and small that I'm missing in my more-so basic program.</p>
  
  <p>Check it below, thanks for any tips.</p>
