Day 25/100 Java

Morning research done.

Day 25/100

Language:
JAVA

Time Period Spent:
2 hrs

Course Taken:
Udemy: Java Programming Masterclass - Tim Buchalka

Todays Learning:

  • Research on Arrays.
  • Reaseach on ArrayList.
  • Reaseach on Collections.
  • Rewatch array recap.
  • Rewatch ArrayList.

Additional Notes:
This morning was spent being productive, I recapped on functionality on Arrays and ArrayLists. This helped me in the underlaying use-cases of ArrayList and the difference between, Arrays and ArrayLists. There is a subtle difference that Arrays are a predefined length, while ArrayLists are malleable. I also discovered that I can use the collections import to do the reverse and sorting of an ArrayList of me. Not sure about how this affects speed compared to an Array ForLoop reverse, will need to test this. Overall I am satisfied to continue on the course with this understanding.
