So the following code wouldnt work. The javalang package is always imported by default and does not need to be imported by an import statement. Suppose you want to import all the classes interfaces or enums from the package.

Hence we will not have to write the functionality of adding two integers again. Java has an import statement that allows you to import an entire package as in earlier examples or use only certain classes and interfaces defined in the package. Technically you can as shown in Sharique Abdullahs answer through reflection API but classes from the unnamed namespace are not in scope in an import declaration Prior to J2SE 14 you could import classes from the default package using a syntax like this.

Import particular class 3. That static imports are not possible from a class in the default package. Class A and class B both classes are packageless in default package.

String userName myObjnextLine. You cant use classes in the default package from a named package. I have 2 classes.

Cannot resolve symbol. Of course the important bit of this question is that the class and its code has to be in the default packageAs of now any answer other than to use reflection API really an overkill for something this simple is not a solution.

The Java API is very extensive contains classes which can perform almost all your programming tasks right from Data Structure Manipulation to Networking. 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. Its not a good idea to put classes in the default package - you should always put your classes in a.

This feature was removed in Java 5. We have specified a package to be used and hence the compiler will go and look for this package. Import all classes and interface 2.

I compiled Test1java that declares and initialises the static final int CONSTANT and then subsequently compiled Test2java that attempts to import static Test1CONSTANT.
