Simple string parser for Java

Introduction

Sometimes it is required to parse a string like it can be done with the C scanf(). I developed a similar function for Java with the extension that this parser can also handle strings enclosed in " or ' correctly.

Features

• parse integer, float, double, char, strings, boolean values

• printf-like format strings

• can handle strings parts enclosed in " or '

• partial parsing of string

• escape and unescape strings which include " or '

Requirements

• Java JDK 1.5 or newer

Examples

public class StringParserDemo
{
  public static void main(String[] args)
  {
    String s = "Hello World: \"how are you?\" - 123 4.5";
    Object[] data = new Object[3];

    if (StringParser.parse(s,"Hello World: %S - %d %f",data,StringParser.QUOTE_CHARS))
    {
      System.out.printf("%s\n",(String)data[0]);
      System.out.printf("%d\n",(Integer)data[1]);
      System.out.printf("%f\n",(Double)data[2]);
    }
  }
}

Compile

Just import StringParser in your Java application source code.

Note: please have a look in StringParser.java for details!
