How Do I Escape the Dot Character for Accurate String Splitting in Java?

Escaping Characters for String Splitting

When splitting a string on a dot (.), it's important to consider the special meaning of the dot in regular expressions. By default, the dot matches any character, which may not be desirable.

To split a string on a literal dot, escape the dot using a backslash (). Here's how you can do it:

String filename = "file.txt";
String[] parts = filename.split("\.");
// Access the first part of the string
String firstPart = parts[0];

By escaping the dot, we instruct the split method to treat it as a literal character rather than a regular expression meta character. As a result, the string will be split at the exact location of the dot, and the first part can be accessed using parts[0].
