Be able to explain what variables are. Understand variable types, allowed names, and valid values. Know how to create and use string, integer, floating-point, and boolean variables.

The lab template contains a program that prints the following:

2 tickets: $28.00
2 hotdogs, 2 popcorn, 2 sodas: $18.00
1 autographed baseball $45.00
real conversation with 11 year old son: priceless
true

Ignore the code that you don't fully recognize and concentrate on changing the variables to alter the MasterCard Priceless script to say:

3 tickets: $42.00
3 hotdogs, 3 popcorn, 3 sodas: $27.00
2 autographed baseball $90.00
watching the Giants win: priceless
false

Take note of the various variables and their data types. Write a brief summary in this section of the README.md file listing the:

• Variable name

• Its data type

• and example values you can assign them.

• In this lab, one of the Variable names is under the main string "Tickets". The data type for "Tickets" is a float. The value for this float is 14. Values can be assigned as numbers or text.

Next give TWO example variable names and TWO example variable assignments that are WRONG and explain why.

• Hint: your IDE can help you discover these!

• Almost any name can be used to assign to a Variable. In this lab some other Variables are named "Sodas" and "hotdogs". "Keywords" are five words that cannot be used as variable names. The five keywords are public, class, static, void, and int.

Pick several of the Java format specifiers below and define variables of the correct type utilize sout and String.format to view the resulting formats.

• Commit your working code
• Push it to your Remote/origin branch (i.e. GitHub)
• Then issue a Pull request to the instructor branch
  • Make sure to save the Pull request URL and submit it for the lab.
