Programming :: Java - Can't "Formatter.format"
Dec 24, 2010I met a trouble in Java, that is the method of "Formatter.format". The "System.out.printf" can output what I want, but why can't "Formatter.format" do that in the under way?

View 5 Replies View RelatedProgramming :: Best Way To Transform XML Format?
Sep 10, 2010I'm looking for some expert opinion on sed/script to work out the best way to transform one xml format into another however there are a few complexities around translation.
The extra complexities are to:
1) Take the start and stop time (YYYYMMDDHHMMSS) and convert to start time to unix time plus output the difference in seconds between both times.
2) Oid, tsid and sid are found by looking up an external file and finding the value against the channel. For example one of the lines in the file will be 2:806:27e2=channel1
Is there any way to write piped sed commands that can do this? If not, any ideas how the script should look like?
Input File
Code:
<programme start="20100910060000 +0100" stop="20100910061000 +0100" channel="channel1">
<title lang="en">This is the title</title>
<desc>This is the description</desc>
</programme>
Output File
Code:
<service oid="0002" tsid="0806" sid="27e2">
<event id="0">
<name lang="OFF" string="This is the title"/>
<text lang="OFF" string="This is the description"/>
<time start_time="1284098400" duration="600"/>
</event>
</service>
Look up file for oid, tsid and sid
Code:
2:806:27e2=channel1
2:756:37a3=channel2
5:4a06:42e5=channel3

Programming :: Sed - Series Of Files In The Format
Sep 21, 2009I have a series of files in the format:

So far so simple, but some of the values might have commas in them, which means they'll be split up. Is there a way to change this so that only commas not within quotes will be replaced with ? (e.g. make sed count number of " and if it finds a , after counting an odd number of " then ignore it?)

View 2 Replies View RelatedProgramming :: Stick With Java?
May 12, 2011Situation: this semester I took an class called Introduction to Software Design with Java.It was my first intro to programming. The class had a very odd structure:1. The text was extremely high level. The first few chapters were all about object oriented programming, how objects interact, all about specification, etc (without ever talking about implementation).2. The lecture simply followed (directly) the text. And as a result was rather uninteresting.3. While highly theoretical (in that it was very high level approach), we never talked about how the computer was dealing with the information, etc.as all very "hand waving/magic" approach.
Okay so enough of the complaints:Question: This summer I'd like to dive a bit more into a language mainly out of frustration and lack of a good book. I'm thinking perhaps a lower level language.1. Would C++ be a good second language? Or should I give Java more time?2. If I am going to go with something else, is C++ sufficiently different, or should I go with C

View 10 Replies View RelatedProgramming :: IEEE Floating Point Format?
Jun 5, 2011I'm reading a book on assembly, and it talks a bit about the IEEE floating point format.
Quote:
To summarize, the following steps are used to convert a decimal number to IEEE single format: 1. The leading bit of the floating point format is 0 for a positive number and 1 for a negative number. 2. Write the unsigned number in binary. 3. Write the binary number in binary scientific notation f23.f22 ... f0 2^e, where f23 = 1. There are 24 fraction bits, but it is not necessary to write trailing 0's. 4. Add a bias of 127 to the exponent e. This sum, in binary form, is the next 8 bits of the answer, following the sign bit. (Adding a bias is an alternative to storing the exponent as a signed number.) 5. The fraction bits f22f21 ... f0 form the last 23 bits of the floating point number. The leading bit f23 (which is always 1) is dropped.
