Creating User-defined Package
Java supports a keyword called “package” which is used to create user-defined packages in Java programming.
The general syntax to create a package is as:

package packageName;
Here, packageName is the name of package. The package statement must be the first line in a Java source code
file followed by one or more classes. For example:

package myPackage;
public class A {
// class body
}
In this example, myPackage is the name of package. The statement “package myPackage;” signifies that the
class “A” belongs to the “myPackage” package.
