In this article we will show you the solution of how to use nextline in java, the nextLine() function in Java is a useful resource for reading user input. It is a member of the Scanner class, allowing users access to a number of input parsing methods.

By using the nextLine() method, you can read an entire line of text that the user has provided, together with any spaces or other special characters, and save it as a string.

There are a few easy steps you must do in order to use nextLine().

To handle the input, you must first build a Scanner class instance.

After that, you may get the user's most recent text entry by using the nextLine() method. We will now discuss the idea of using nextline in Java.

Step By Step Guide On How To Use Nextline In Java :-

import java.util.Scanner;
public class NextLineExample {
    public static void main(String[] args) {
        // Create a Scanner object to handle input
        Scanner scanner = new Scanner(System.in);
        // Prompt the user to enter their name
        System.out.print("Enter your name: ");
        String name = scanner.nextLine();
        // Prompt the user to enter their age
        System.out.print("Enter your age: ");
        int age = scanner.nextInt();
        // Consume the remaining newline character after nextInt()
        scanner.nextLine();
        // Prompt the user to enter their address
        System.out.print("Enter your address: ");
        String address = scanner.nextLine();
        // Display the collected information
        System.out.println("\nPersonal Details:");
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("Address: " + address);
        // Close the Scanner object
        scanner.close();
    }
}

1. You can see in this example how we wrote the Java code to demonstrate how to utilise nextline in Java.
2. The 'Scanner' class from the 'java.util' package is first imported. We may read input from numerous sources thanks to this class.
3. We create a class called "NextLineExample" that has a "main" function that acts as the program's entry point.
4. We build a 'Scanner' object called'scanner' inside the'main' method to manage user input.
5. We supply 'System.in' as the argument in order to indicate how we are reading data from the standard input (keyboard).
6. Using "System.out.print()," we ask the user to enter their name, and then we use "scanner.nextLine()" to store the data in a string variable called "name."
7. The entire line of text submitted by the user, including any spaces, is read by this method and returned as a string.
8. We then use System.out.print() to ask the user for their age and scanner.nextInt() to read an integer value.
9. The next integer is read from the input by the 'nextInt()' method. But there is a warning.
10. A newline character ('n') is left in the input buffer after reading the number.
11. We immediately call "scanner.nextLine()" after "scanner.nextInt()" to consume this newline character.
12. After that, we use "System.out.print()" to ask the user for their address before using "scanner.nextLine()" to read the entire line of text.
13. The user is now able to enter multi-word addresses.
14. After obtaining all the data, we use 'System.out.println()' to print the details out for viewing.
15. Address, name, and age are all included in the data.
16. The 'Scanner' object is finally closed using'scanner.close()' to free up system resources.

Conclusion :-

As a result, we have successfully acquired the knowledge necessary to use nextline in Java.

We also discovered that the Scanner class' nextLine() function in Java is a useful tool for gathering user input.

We are able to read entire lines of text, including spaces as well as special characters, as well as save them as strings thanks to this technique.

For interactive Java programs that involve receiving user input from the console, the nextLine() method is a crucial component due to its ease and versatility.

I hope this article on how to use nextline in java helps you and the steps and method mentioned above are easy to follow and implement.
