Java Escaping String for Storage in csv file

I suggest you use one of the libraries recommended by the post(s) here. While it may seem easy to write your own CSV creator/parser, you are going to run into issues where you need to handle scenarios such as user strings with commas or quotes in them, which can sometimes be quite cumbersome. I used the following libraries and they worked fine:-

• com.Ostermiller.util Java Utilities
• opencsv

For anyone looking for code:
add this to your pom.xml

<dependency>
    <groupId>commons-lang</groupId>
    <artifactId>commons-lang</artifactId>
    <version>2.6</version>
</dependency>

Then use:

 String escaped = StringEscapeUtils.escapeCsv("tHIS String 'needs escaping'");
 System.out.println(escaped); //safe for csv

UPD: as of version 3.6, StringEscapeUtils in commons-lang deprecated, so you have to use commons-text instead:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-text</artifactId>
    <version>1.6</version>
</dependency>
