Splitting String into an int Array in Java

A practical guide demonstrating how to convert comma-separated numeric strings into integer arrays in Java. Covers the split() method for breaking strings at delimiters, trimming whitespace, and converting string elements to integers. Includes examples with different separators (commas, semicolons, pipes) and explains how to handle regex special characters using backslash escaping. The technique applies to common scenarios like processing user input, reading file data, and handling numeric datasets.
