File Processing

Line-based processing uses nextLine() to read entire lines, preserving spacing within the line. Token-based processing uses next() to read individual tokens separated by whitespace, losing line spacing. The template shows how to combine both by breaking a file into lines and then scanning each line.

FileNotFoundException is a checked exception that must be handled. The template demonstrates using 'throws FileNotFoundException' in the main method signature, or you can use a try-catch block to handle it gracefully.

The input cursor tracks the current position in the input source. When a Scanner is first constructed, the cursor is at the beginning. As you call methods like next() or nextLine(), the cursor moves forward; it does not support moving backward. The template explains this with the numbers.dat example.

Yes, this File Processing mind map is ideal for Java students and educators. It covers file-reading basics, token and line-based processing, output with PrintStream, and a case study on zip code lookup, providing a comprehensive reference.

The template identifies boilerplate code as code that tends to be the same for every program, such as constructing a Scanner with a File object, importing java.io.* and java.util.*, and declaring throws FileNotFoundException. The getInput method is given as an example.
