Introduction |
|
| |
If you have installed the google tool bar on your browser you will notice a button that does spell checks. This tutorial will provide
you with a Java class that mimics the calls of the toolbar button. This is not an official API.
DISCLAIMER:
You are following this tutorial at your own risk. If anything
blows up do some meditation before assigning blame. |

The Code |
|
| |
1) You can download the full source code from here:
Source code file and unzip it to C:\googlespellchecker |
|
| |
|
|
| |
2) The zip file consists of one src file, compile batch file, run batch file.
Assuming you have Java installed the only thing that you need to do is change the path for javac in the compile.bat if its different.
|
|
| |
|
|
| |
3) From a command prompt go to C:\googlespellchecker and execute the compile.bat. Make sure you
get a .class file. You can change the string that you want to be spell checked in the main method. Next execute the run.bat file. |

The above will give an output as follows: |

4 <c o="0" l="5" s="1">hello heel Helli halo heal</c>
5 <c o="6" l="5" s="1">world wield wild wiled whirled</c>
6 </spellresult>

The 'o' indicates the offset from the start of your string to the misspelled word.
'l' is the length of the misspelled word.
's' seems to be a confidence indicator |
