1.2 Using Objects


  1. Describe the behavior of a given segment of program code.
  2. Determine code that would be used to interact with completed program code.
  3. Write program code to create objects of a class and call methods.
  4. Determine the result or output based on the statement execution order in a code segment containing method calls.
  5. Apply the meaning of specific operators.

Essential Questions

  1. How can we simulate election results using existing program code?
  2. How are appropriate variables chosen to represent a remote control?
  3. How do the games we play simulate randomness?
