How to use delimiter with Scanner class in Java? | Java IO | Java Tutorial

Welcome to our Java tutorial on using delimiters with the `Scanner` class in Java!

In this video, you'll learn how to customize and set delimiters when using the `Scanner` class to parse input streams efficiently.

**Overview**:
The `Scanner` class in Java provides a convenient way to tokenize and parse input data into tokens based on specified delimiters. Delimiters are characters or patterns used to separate tokens when reading input from sources such as standard input, files, or other streams.

**Key Concepts**:
- Delimiters in the `Scanner` class are defined using the `useDelimiter()` method, allowing you to specify a regular expression pattern or a simple string as the delimiter.
- Customizing delimiters enables flexible parsing of input data, allowing you to extract tokens based on specific patterns or separators.

**Why Use Delimiters with Scanner Class?**:
- By setting delimiters, you can control how input data is tokenized and parsed, making it easier to handle different types of input formats.
- Delimiters help in processing structured input data, such as CSV files, where tokens are separated by commas or other characters.

**Java Code Examples**:
We'll demonstrate how to use delimiters with the `Scanner` class through practical examples. You'll learn how to:
- Initialize a `Scanner` object and set custom delimiters using the `useDelimiter()` method.
- Parse input data into tokens based on specified delimiters and extract meaningful information from the input stream.

By the end of this tutorial, you'll have a solid understanding of how to leverage delimiters with the `Scanner` class to parse input streams effectively in your Java programs, empowering you to handle different input formats with ease.
