Import a custom class in Java

Question

How do I import a class I wrote in a different file  All my classes are under the same package

User · Answer

If your classes are in the same package  you won t need to import  To call a method from class B in class A  you should use classB methodName arg

In the same package you don t need to import the class   Otherwise  it is very easy  In Eclipse or NetBeans just write the class you want to use and press on Ctrl   Space  The IDE will automatically import the class   General information   You can import a class with import keyword after package information   Example   package your package    import anotherpackage anotherclass   public class Your Class               private Vector variable              You can instance the class with   Anotherclass foo   new Anotherclass

First off  avoid using the default package   Second of all  you don t need to import the class  it s in the same package

According Oracle and Sun doc  a class can use all classes from its own package and all public classes from other packages  You can access the public classes in another package in two ways     The first is simply to add the full package name in front of every class name  For example   java util Date today   new java util Date    The simpler  and more common  approach is to use the import statement  The point of the import statement is to give you a shorthand to refer to the classes in the package  Once you use import  you no longer have to give the classes their full names  You can import a specific class or the whole package  You place import statements at the top of your source files  but below any package statements   For example  you can import all classes in the java util package with the statement Then you can use without a package prefix   import java util        Use class in your code with this manner  Date today   new Date      As you mentioned in your question that your classes are under the same package  you should not have any problem  it is better just to use class name

I see the picture  and all your classes are in the same package  So you don t have to import  you can create a new instance without the import sentence

User · Answer

If all of your classes are in the same package  you shouldn t need to import them   Simply instantiate the object like so    CustomObject myObject   new CustomObject

User · Answer

Import by using the import keyword   import package myclass    But since it s the default package and same  you just create a new instance like   elf ob   new elf      Instance of elf class
