Facts about Computer !

  1. Most "free" anti virus programs that come preinstalled on laptops are also pretty bad and generally would try to force you to buy them after the initial "free" period has expired.
  2. Norton takes A LOT of resources,I've been sporting Microsoft Security Essentials since it's release and have yet to have anything get through onto my laptop or PC, and I take my laptop to public wifi hot spots a few times a week.

-Xlint:deprecation | deprecated API | use unchecked or unsafe operations

-
Note: Some input files use or override a deprecated API. ( It simply means that you are calling methods which have been marked with a  @Deprecated  annotation.) Note: Recompile with -Xlint:deprecation for details. (Probably, that is because you need to declare a List object, say (e.g.), without omitting '<' and '>': List < Integer > list = new ArrayList < Integer >();) Note: Some input files use unchecked or unsafe operations. ( for example when you call a function that returns Generic Collections and you don't specify the generic parameters yourself. for a function List < String > getNames () List names = obj . getNames (); will generate this error. To solve it you would just add the parameters List < String > names = obj . getNames ();) Note: Recompile with -Xlint:unchecked for details. ( From what I can tell in the docs, you can't do it on the command-line. According to the  javac  documentati

Error ? Caused by: java.time.temporal.UnsupportedTemporalTypeException: Unsupported field: MinuteOfHour Solution : LocalDate  represents just a date, not a DateTime. So "HH:mm:ss" make no sense when formatting a  LocalDate . Use a  LocalDateTime  instead, assuming you want to represent both a date and time. Take a close look !! MinuteOfHour is unsupported /** Map of letters to fields. */ private static final Map < Character , TemporalField > FIELD_MAP = new HashMap <>(); static { FIELD_MAP . put ( 'G' , ChronoField .

Jasper Raport bug on mac

net.sf.jasperreports.engine.query.JRJdbcQueryExecuter <init> WARNING: The supplied java.sql.Connection object is null. I've been using Jaspersoft paired with Java beans for my reports and everything is going well. It was only when I checked the logs, which can be viewed by the client, that I noticed that there is something wrong. In the code below, the highlighted line, it checks if there is an SQL connection.   Since I don't use SQL it returns a warning message:  JRJdbcQueryExecuter - The supplied java.sql.Connection object is null.  How can the SQL connection validation be prevented? this part of code works for me !!! JasperDesign jd = JRXmlLoader . load ( "C:\\Users\\USER\\DOCUMENTS\\ATHLETICS\\participants.jrxml" ); String sql = "SET @s:=0; select @s:=@s+1 POSITION, CHESTNUMBER AS 'CHEST NUMBER', FULLNAMES AS 'PARTICIPANT', TEAM AS 'TEAM'," + " PHONE AS 'PHONE'
