Sharpen skills: 11 project ideas in Java

Want as quickly as possible to learn Java? Then we recommend to pay more attention to practice! Theory itself is ineffective, and the only real coding is able to bring you to a dream career.

Entry level

1. “TIC TAC toe”

Well-known and very simple game. Not only for players but for developers. To make his version, we recommend you to bind the Java Class to a GUI or to integrate it directly into the console program. The class code is divided into three sections: the functions of the player, panel, and victory conditions.

2. The system ATM

Create it using the Java interface of the ATM. In the process, you will need to do 5 classes: for the account of its owner, transactions, banking institutions and ATM.
