Java Non Printable Ascii Characters

What are Non Printable ASCII Characters?

In Java, ASCII characters are used to represent a wide range of symbols, including letters, digits, and special characters. However, there are some ASCII characters that are not printable, meaning they do not have a visual representation. These characters are used for control purposes, such as formatting text, indicating the start or end of a file, or signaling the presence of an error.

Non printable ASCII characters are used in various contexts, including data transmission, file formatting, and system communication. They can be used to separate data fields, indicate the start or end of a record, or to signal the presence of an error. For example, the ASCII character 10 (line feed) is used to indicate the start of a new line, while the ASCII character 13 (carriage return) is used to return the cursor to the beginning of the line.
