Hence, you need to import the subpackage as well. Package inside the package is called the subpackage. It should be created to categorize the package further. Let's take an example, Sun Microsystem has definded a package named java that contains many classes like System, String, Reader, Writer, Socket etc.

These classes represent a particular group e. So, Sun has subcategorized the java package into subpackages such as lang, net, io etc. There is a scenario, I want to put the class file of A.

Python Pillow. Python Turtle. We define a class and object and later compile this it in our package p1. After compilation, we execute the code as a java package. The compilation is completed. A class file c1 is created.

However, no package is created? Next step has the solution. Step 4 Now we have to create a package, use the command. Step 5 When you execute the code, it creates a package p1. When you open the java package p1 inside you will see the c1. In our case file will be saved in parent directory which is C Drive. Then we will modify our code as. Step 9 To execute the code mention the fully qualified name of the class i.

To create an object of a class bundled in a package , in your code, you have to use its fully qualified name. But, it could become tedious to type the long dot-separated package path name for every class you want to use.

Then create the MyClass inside the directory with the first statement being the package names. Now we can use the MyClass class in our program. Using Static Import Static import is a feature introduced in Java programming language versions 5 and above that allows members fields and methods defined in a class as public static to be used in Java code without specifying the class in which the field is defined. For example both, java. So if we import both packages in program as follows: import java.

Date or java. The compiler will not be able to figure out which Date class do we want. This problem can be solved by using a specific import statement: import java.

Date; import java. For Example:. Skip to content. Change Language. Related Articles. Basics of Java. Operators in Java. Packages in Java. Flow Control in Java. Loops in Java. Jump Statements in Java.
