Working with branches in Git
● Clone the project (if you has not do it yet)
● Create new local branch
○ based on commit 52d493a7 (current head of master branch)
○ with name week03-group0X-roomY (0X is seminar group, Y is breakout room number)
○ If you from group PV168/01 and breakout room 3, branch name is week03-group01-room3
● Pavel Hrdina or Petr Adámek will give you write access to calculator
repository
○ Only one person per breakout room - the one who will use the computer for coding
○ Petr or Pavel will visit your breakout room to ask who is this person
○ In the meantime work on other tasks
● Push the branch to origin repository
Seminar task: Calculator refactoring
● Perform the steps from previous slide (create and push git branch)
● Do the following refactorings, commit and push each step (with reasonable
granularity)
● Do not forget to execute tests after each step!
○ Keep in mind that main(String[]) method is not covered with tests
● Find and solve occurences of these code smells
○ Mysterious name (s0, s1, s2, l, b?, te, f, p)
○ Duplicated Code (with operation evaluation)
○ Long function (actionPerformed(...), main(...))
○ Comments (Note: some of them can be resolved together with other refactorings)
○ Duplicated Code (button creation in main method; do this as the last one)
