Java Lessons 9 – 12 Mr. Kalmes

Learning Targets I will be able to utilize variables I will be able to fix logical errors I will be able to construct variable shortcuts I will be able to explain boolean expressions

Lesson 9 Create the following program Change the program to convert lbs to kgs and inches to meters

Lesson 10 Logical Error: a flaw with the flow of instructions, so that the output is not what was trying to be accomplished.

Lesson 10

Lesson 11 Shortcuts: x += n or x -= n or x *= n or x /= n or x %= n x++ or x-- Be careful: x =+ and x=- are different

Lesson 11

Lesson 12 Boolean Variables: Can not hold numbers or words Can only hold two values – True or False They are used to perform logical calculations

Lesson 12

Exit Slip What is a logical error What’s the difference between += and =+ How do you think you will use boolean expressions?
