How to check if a file is editable in PeopleCode

How do we check if a file is editable in PeopleCode? This was a question asked in ITToolbox forum.

We can do this easily using Java File class object.

 &myFileToCheck = "C:\Temp\MYFILE.TXT";  
 Local JavaObject &file = CreateJavaObject("java.io.File", &myFileToCheck);  
 If &file.canWrite() Then  
   /*Normal processing*/  
   MessageBox(%MsgStyle_OK, "", 0, 0, "File is editable!!");  
 Else  
   /*Error processing*/  
   MessageBox(%MsgStyle_OK, "", 0, 0, "File is Read Only!!");  
 End-If;
