This article delves into the core distinctions between the next() and nextLine() methods of the Scanner class in Java when handling user input. Starting with a common programming issue—where Scanner reads only the first word of an input string instead of the entire line—it analyzes the working principles, applicable scenarios, and potential pitfalls of both methods. The article first explains the root cause: the next() method defaults to using whitespace characters (e.g., spaces, tabs) as delimiters, reading only the next token, while nextLine() reads the entire input line, including spaces, up to a newline character. Through code examples, it contrasts the behaviors of both methods, demonstrating how to correctly use nextLine() to capture complete strings with spaces. Additionally, the article discusses input buffer issues that may arise when mixing next() and nextLine(), offering solutions such as using an extra nextLine() call to clear the buffer. Finally, it summarizes best practices, emphasizing the selection of appropriate methods based on input needs and recommending the use of the trim() method to handle potential leading or trailing spaces after reading strings. This article aims to help developers deeply understand Scanner's input mechanisms, avoid common errors, and enhance code robustness.
