Question on checking a string for letters. help!
im doing a method to check if a string given by the user contains something other then a alphabet. what i did was use the Character isLetter method and simply did a charAt(count) of the string given, problem is when i was testing my method i realize that if i spaced out the string such as "abc de" it would print out my error message for that method but it shouldnt print the error msg since it contains only letters. any suggestions on how to use the isLetter() and have it accept whitespace? the method works if i just did abcde but not abc de. thanks in advance
Try using
if (Character.isWhitespace(c) || Character.isLetter(c)){
// it is good
else {
// no good
}where c is your character. So this way you allow both white space and letter.

Easy question about checking a string
hi guys i have a problem that im sure most of you will know and im probably doing something silly, I have a record and am wanting to check the values in some fields so i have:
IF Rec1.next_record = 'Renault' AND Rec1.prev_record != 'Vauxhall'
the != part doesnt seem to be working, should i be using a different method to check if the string is not equal to the given text?
Thanks.thats the problem then, the value is null, so you would think if i done
if Rec1.prev_record = NULL it should work? though it doesnt appear to. Would you have any ideas on that?
Thanks for the information, quite helpfull. -

I have a question about the licensing requirements for Oracle Help.
I am writing the on-line help to support a commercial application which will be charged for. can I use Oracle Help for developing on-line help?
Thanks.
baiHi,
Q: I read the license text on the download page... I didn't see any reference to the rights to re-distribute the icebrowser that comes with the Oracle Help. Does one need to obtain a separate license with Icesoft the maker of IceBrowser ?
Q: Related to a message posted earlier about Oracle's plan for Oracle Help... I can tell from the messages folks feel the Oracle Help has some advantages over Sun Java Help, and it can be considered as a replacement for Sun Java Help. However, in order to migrate from Sun Java Help to Oracle Help, it's important to understand the roadmap.. a roadmap will make it clear that Oracle is committed and helps users justify a migration.
Q: Also, since Oracle is committed to Eclipse... what is going to happen to Oracle's commitment to Oracle Help, if people start building applications using the Eclipse Rich Client Platform and use the Eclipse Help system ?
Thanks in advance for your responses,

Check string for two special characters back to back
Hey all so I need to check if a string has 2 backslashes back to back ("\\"). So the string "\\computername\c$\file" would match but the string "C:\file\path" would not. I've tried contains, match, and like. I've tried the code
below which does work but gives me a false positive when I have a string like this "\computername\file\path".
$com = "\\computername\C$"
if($com -match "\\"){
Write-Host true
}else{
Write-Host false
Thanks for any help!In Regex ^ matches the starting position of a string. \ is a special character in Regex so you need to escape it with another \, so since you want double backslash \\, you need to escape twice \\\\, so ultimately ^\\\\ reads, at the start of the string
find \\

i am going to buy unlocked iphone 5.. i will be going to india nxt months and will stay there for a while... so my question is will i get warrenty in india.. and will there be any problem with using indian sims..?? thnx for the help..
The warranty for the iPhone is not and has never been International.
Warranty and support are ONLY valid in the country of origin. The only exception is the EU where the entire EU is treated as one country.
If the device will be used in India, buy it in India.
An unlocked iPhone will work on any supported GSM carrier world wide. The LTE portion of a US purchased, unlocked iPhone is unlikely to work outside North America as it does not support the appropriate bands used in other countries. -
