[Solved] How can I re-run java code from the java program?


Why dont you use recursion. put the file writing code into one method.
Giving blueprint below please try to implement that way.

    public class CSV { 
      String data1; 
      String data2; 
      boolean runnung=false; 
      int globalvariable = 1;
      public void fileWrite(){  
               FileInputStream ar= new FileInputStream("filelocation");  
               FileWriter dr= new Filewriter("datafile"+globalvariable.csv"); 
               dr.close(); 
               //while (running) { 
                  if (data=some number) { 
                      fileWrite();
                  } else { 
                      result=data1+data2; 
                  } 
                  ar.close(); 
               //} 
           }
      } 

Hope this will help you.
