• Define in a Class the following data types
  • Demonstrate use of Primitives: int, double, boolean, string
  • Demonstrate use of Wrapper Class object: String
  • Describe in comments how each data type choice is appropriate to application
  • Perform arithmetic expressions and assignment in a program code Code.org Lesson
  • Determine what is result is in a variable as a result of an data type and expression (ie integer vs double)
  • Perform an arithmetic expressions that uses casting, add comments that show how it produces desired result. Learn more by watching this College Board video
  • Perform compound assignment operator (ie +=), add comments to describe the result of operator

Enter a salary between 0-1,000,000
123123.0
Enter your pay raise
123123.0
Your final salary is: 246246.0, which is around a 100% raise from your original salary. You got a good pay raise!
