Question
Explain the syntax of importing packages in Java with suitable example.
Solution
In Java, packages are used to group related classes, interfaces and sub-packages. Importing packages in Java allows you to use the classes and methods that are part of that package.
The syntax for importing a package in Java is:
import package.name.ClassName; // To import a single class
or
import package.name.*; // To import the whole package
Here's an example:
import java.util.Scanner; // Importing the Scanner class from the java.util package
In this example, the java.util.Scanner class is imported, which means you can create an instance of Scanner without having to fully qualify its name like java.util.Scanner.
Here's how you can use it:
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner myScanner = new Scanner(System.in);
System.out.println("Enter your name: ");
String name = myScanner.nextLine();
System.out.println("Hello, " + name);
}
}
In this code, we import the Scanner class from the java.util package, then use it to get input from the user.
If you want to import all classes from a package, you can use the * wildcard. For example:
import java.util.*; // This imports all classes from the java.util package
This will import all classes and interfaces from the java.util package, so you can use any class from this package without fully qualifying its name.
