List of usage examples for org.apache.commons.lang3 StringEscapeUtils escapeJava

Introduction

In this page you can find the example usage for org.apache.commons.lang3 StringEscapeUtils escapeJava.

Prototype

public static final String escapeJava(final String input) 

Source Link

Document

Escapes the characters in a String using Java String rules.

Deals correctly with quotes and control-chars (tab, backslash, cr, ff, etc.)

So a tab becomes the characters '\\' and 't' .

The only difference between Java strings and JavaScript strings is that in JavaScript, a single quote and forward-slash (/) are escaped.

Example:

 input string: He didn't say, "Stop!"
