Simple Java Exercises for Beginners

In this repository you will find many ways to test your newly learned Javaskills. The StdDraw Framework from Princeton is used several times. That’s why I recommend you take a look at it!

I hope this repo helps many programmers in Java!

The description of the tasks are most above in each Java class. Since these are simple Java tasks, we do not want to program unbound object-oriented here. The description of the tasks are not from me (I found them everywhere on the internet and thought they were good for practicing). Because of this they are sometimes not very clear or leave a lot of room for interpretation.

A detailed description of the Task can be found here

In case you have a good idea for a new tasks please:

• open a new issue and tag it with «Task Idea»
• describe the requirements precise
• let us know why you think that the task could help others and for what it aims for
