r/javahelp on Reddit: Java Practice: Someone give me basic problems!
February 6, 2023 -
Hi there,
I am in the middle of Chapter 2 of my Intro to Java course.
I just completed the "Interest Rate Calculator" portion of the section.
I'm looking for examples (or formulas) to practice writing in Java.
I have already done Area of a Rectangular Prism, Area of a Hexagonal Prism, Wind Speed Calculation etc on my own. Does anyone have a nice source of practice examples that propose a problem for beginners? Or does anyone want to propose a problem example themselves?
Any and all help is appreciated!!!

an interesting way of practicing loops is trying to print patterns on screen. something like: ----- ---- -- - or - --- ----- finding ways of printing patterns like these for any number of lines is pretty good for learning the capabilities of loops and developing logical thinking in general i guess. A good one to try and make could be /\ / \ / \ \ / \/ \/ this is suposed to be a diamond, i didn't know reddit made this with spaces
