[Java] Tools package
Hi ! I'm a java beginner. I was wondering if it was a good idea to create a Tools Package. for example I could create a method say instead of System.out.println (). A method too to display the contents of an Array ... so I could import this toolbox into each of my projects. Thank you in advance for your opinions and good codes to all!

Depends on the scale of your project and the benefit modularization would bring you. For printing arrays, two lines of: for (ArrayType i : yourArray) System.out.print(i + " "); doesn't seem like too much hassle to re-type each time you need it. However, I can totally see why you would need one when you want a method to handle generic datatypes, or when you have to print the array in a formatted way, e.g. in a table, with proper labels, units. Just make sure that modularizing stuff will actually save your time instead of adding complexity to your project.
Hi Frédéric PARENT Yes, it's a very good idea always to create a tools(also called util, short for utility) package. I usually like to have a util package for every project I'm working on, where I put my parsers, date functionalities, etc.
I tried that method of printing. Due to my limited knowledge, I had to create the method multiple times to account for printing strings, integers, doubles, arrays etc. I'm sure there is a better way to be able to pass any data type into a function without making multiple datatypes for each, but that's just a limitation to my toolbox.
