A package as the name suggests is a pack(group) of classes, interfaces and other packages. In java we use packages to organize our classes and interfaces. We have twotypes of packages in Java: built-in packages and the packages we can create (also known as user defined package). In thi...
In Java, a package is a collection of sub-packages, interfaces, and classes of a similar kind. Discover all of its benefits and how it operates through real-world examples.
@[Andrew], When learning basics in Java, we use Scanner class of java.util package, so few people import the package like java.util.* , while few does like java.util.Scanner; I think there is a difference of execution time between both statement of importing all classes of util package...
package Quad2; import java.util.*; import Quard1.*; class Quadratic_equation implements Quard1.Quadratic_Eq{ public static void roots(){ System.out.println("Enter the a,b,c of ax^2+bx+c :"); Scanner scan = new Scanner(System.in); double x[]=new double[3]; for(int i=2;i>=...
Using theScannerclass to get user input: importjava.util.Scanner;classMyClass{publicstaticvoidmain(String[]args){ScannermyObj=newScanner(System.in);System.out.println("Enter username");StringuserName=myObj.nextLine();System.out.println("Username is: "+userName);}} ...

package chp7; import java.io.File; public class Test { public static void main(String [] a) { File myFile = new File("Dude.txt"); } } Importing the packageName.className as shown above allows the shortcut reference to only that class, not other classes in the same package. You can...
the java.util.Date class simply as Date. In C++, the construction analogous to the package mechanism is the namespace feature. Think of the package and import statements in Java as the analogs of the namespace and using directives in C++. ...
In Java, you package classes using the package keyword. In C#, you use the namespace keyword to do exactly the same thing. In the example below, MyClass has been placed into a namespace called MyNameSpace. 1: using System; 2: namespace MyNameSpace{ 3: class MyClass{ 4: static void...
