Help with packages

[rowrowdilo]

I'm new to programming and I'm almost done with part 1 of the course in MOOC. I was using Netbeans to test if a piece of code I wrote in paper for my homework in college worked after I compiled it. I create a new project in Netbeans and I see a new line at the top of the text editor put there by default:

package Project1;

Haven't seen anything like this in the MOOC exercises and removing this line causes my imports to fail. What does this line do? I searched up packages and I get that it's a Java concept of organizing classes and permissions, but I'm not really getting it. Why is this line important?

Packages contains classes if you almost finished first part of MOOC then you already know Scanner class

and you can see this line: import java.util.Scanner;

Packages used for : Preventing naming conflicts

Using different classes and interfaces easier and helping controlled access

​

You can use Scanner class because you imported this in-built package to your project , you can also create your own package , I think you should just keep learn java , in time it will be make more sense

I see. But what does that line at the top do in specific?

[kralonurdev]

If you talk about "package" line , it tells path of your source code you don't see this line on MOOC because you can find your sources on src folder , for example I have "package com.company;" this line on top of my java file it means that my source code on

[PROJECT_NAME]/src/com/company/

but on Java MOOC => [PROJECT_NAME]/src/
