ConnectionDB.java

public   int   insert(String   sql   ,String   fileID,String   typeID){
int   INSERT_RESULT=0;
con   =   getConnection();
ps   =   con.prepareStatement(sql);
ps.setString(1,   fileID);
ps.setString(2,   typeID);
INSERT_RESULT   =   ps.executeUpdate();
return   INSERT_RESULT;
}

The   insert()   was   been   used   by   this:
fileDAO.java

public   boolean   insert(FileInformation   fileInformation)   {
ConnectionDB   connectionDB;
int   INSERT_RESULT_RETURN   ,INSERT_FILE_TYPE_RETURN=   0;
