Any practice projects recommendations for Java ?

I would like to get better at coding and doing the track course, however I want a project to work while I am on the way.

Hi Martin,

These are some resources that I have found useful:

  1. Project Euler
  2. Coding Bat
  3. Thinking in Java 4th Edition

Thinking in Java has practice problems and covers many topics in Java SE.

Hope this helps!

One idea is to take a problem, and find multiple ways of solving it, or then improving it, while you learn more techniques. For example, adding the numbers between 1 and 10. In all seriousness, I had a reason to do this, and figured it would be a good exercise.

You could do 1 + 2 + 3 etc...

Then, use loops to manually do it.

Then, check out the Gauss formula. Which lets you calculate the sums between 1 and n. Sum from 1 to n = n(n + 1) / 2.

Then when you know how to take input from the user, ask for n, and then display the results.

Having your own problem to solve, and making a project to solve that problem, is a great way to learn how to do anything.
