making a java package in the command line

Question

Though it\'s probably reccomended one uses and IDE for coding advanced java projects, I personally prefer running almost entirely command-line (using gedit as a text-editor)

Answer 1

// to create a new directory and a subfolder that will be your package

$ mkdir -p parent/child 

// to move into it :

$ cd parent/child                    

//to create an empty java file

$ touch MyClass.java

//to edit current file

$ nano MyClass.java

package child; 
 public class MyClass { 
}

PS: The directory structure on your computer is related to the package name. That means when you edit .java file it needs to have a package declaration(your package) otherwise you will have a default package (ex: java.util.*).
