java import class from default package

Thursday, May 5, 2022 Edit

You cant import a class from a default package. It is because Java compiler imports the javalang package by default in which String class is defined.

What I would try is a sort of proxy -- put your code into a package which anything can use but if you really need something in the default package make that a very simple class which forwards calls to the class with the real code.

. Its a compile time error. Classes that are included automatically are in javalang and can be imported explicitly import javalangString but would be redundant. So I have did a static import.

After that use the import statement inside Testjava like this. Show activity on this post. For Reflections You Can Visit SO link.

I have a class Student_results in the package Students_Record and I want to import that to a class in the package Forgot. Project. Public class A public static int x 10.

If you omit the package statement while writing the class definition the class name is. Problem is your class student has default modifier which restrict the access level upto same packagenot accessible outside the package project1 to package project2. Utiljava is present under the same directory as ListOfNumbersjava.

How do I do that so that it compiles. To import them you need to create separate import. Or you can use reflections.

If you dont declare the package it gets added to the default package like so. When I try to access writeList from a tester class I get the below error. If we want to check it is true or not we can decompile the Java program.

I exported this project into hellojar. Technically you can as shown in Sharique Abdullahs answer through reflection API but classes from the unnamed. Unfortunately you cant import a class without it being in a package.

It means that if a class is defined in the default package meaning it doesnt have any package definition then you cant import its static methods in another class. It means that it will not import classes from its subpackages like yourpackageexceptions. You cannot import a class from a default package basically since the import operation needs the package name.

So there are only two way to fix this problem. See the Java Specification. You cant use classes in the default package from a named package.

If you do not. Every class has a package. The following is not compiling.

I have created a project and Hellojava file without package name public class Hello public String sayHello return Say Hello. You have to create a package and place the class in that. Technically you can as shown in Sharique Abdullahs answer through reflection API but classes from the.

You cant use classes in the default package from a named package. This is one of the reasons its highly discouraged. In every Java program there can be one unnamed package which is simply a package with no name.

If you want to keep the package within the same directory you can use the dot. You cannot import the default package since it has no importable path. Classes in the same project can be imported into any other class in the same project without any import statement in the particular class of the project.

Public class B public static void main String.
