How to Take Multiple String Input in Java Using Scanner?

Java is a versatile and widely-used programming language known for its robustness and flexibility. It allows developers to create a wide range of applications, from simple command-line tools to complex web applications. One common task in Java programming is taking multiple string inputs from users or external sources. In this article, we will explore various methods to accomplish this task using the Scanner class. Whether you’re a beginner or an experienced Java developer, you’ll find valuable insights and practical tips to streamline your coding process.

How to Take Multiple String Input in Java Using Scanner

To take multiple string inputs in Java using the Scanner class, you can follow these steps:

  1. Import the Scanner Class: Start by importing the Scanner class at the beginning of your Java program. This class is part of the java.util package, so you should include the following import statement:
    import java.util.Scanner;
  2. Create a Scanner Object: Next, create an instance of the Scanner class. This object will be used to read input from various sources, such as the keyboard or files.
    Scanner scanner = new Scanner(;
  3. Prompt for Input: Display a prompt message to inform the user about the expected input. This step is essential for clarity and user-friendliness.
    System.out.print("Enter your first string: ");
  4. Read String Inputs: To read a string input, use the next() method of the Scanner object. It reads a single token (word) until a space or newline character is encountered.
    String input1 =;
  5. Repeat for Additional Inputs: If you need to read multiple string inputs, repeat the above steps by changing the prompt message and variable names.
    System.out.print("Enter your second string: ");
    String input2 =;
  6. Close the Scanner: To prevent resource leaks, it’s essential to close the Scanner object when you’re done with it.

Common Pitfalls to Avoid

When working with the Scanner class to take multiple string inputs in Java, there are some common pitfalls to be aware of:

Input Mismatch Exception

If the expected input type doesn’t match the actual input, it can lead to an InputMismatchException. To avoid this, ensure that the input validation matches your expectations.

No Error Handling

Failing to handle exceptions can result in runtime errors. Always include error-handling mechanisms, such as try-catch blocks, to handle unexpected input gracefully.

Resource Leaks

Forgetting to close the Scanner object can lead to resource leaks, which may slow down your program or cause it to behave unpredictably. Always close the scanner when you’re finished with it.


Q: Can I use Scanner to read numeric input as well?

A: Yes, the Scanner class can be used to read various types of input, including integers and floating-point numbers. You can use methods like nextInt() and nextDouble() for that purpose.

Q: What should I do if I want to read an entire line of text as input?

A: To read an entire line of text, use the nextLine() method of the Scanner class. It will capture the entire line, including spaces.

Q: Is there a way to check if the user pressed the Enter key without entering any text?

A: Yes, you can use the hasNextLine() method to check if there’s any input left without consuming it.

Q: Can I use Scanner to read input from a file?

A: Absolutely! Instead of passing as the argument when creating a Scanner object, you can pass a File object to read input from a file.

Q: What is the difference between next() and nextLine() methods?

A: The next() method reads a single token (word), while the nextLine() method reads an entire line of text, including spaces.

Q: Are there any alternatives to Scanner for reading input in Java?

A: Yes, other alternatives include using the BufferedReader class or third-party libraries like Apache Commons IO for more advanced input operations.


In this comprehensive guide, we’ve explored how to take multiple string inputs in Java using the Scanner class. We’ve covered essential steps, common pitfalls to avoid, and provided answers to frequently asked questions. By following these guidelines, you can efficiently gather string inputs for your Java applications, enhancing their usability and interactivity.

Now that you’ve learned the art of taking multiple string inputs in Java, you’re ready to embark on your programming journey with confidence. Feel free to experiment, practice, and apply this knowledge to your Java projects.
