So - working on some new document composition tasks today, and realised my life would be made easier if I could have an application to allow me to compare two documents and highlight the differences...I know I could use a number of other tools, even word compare but it would be more fun if I could do it myself. Plus - there's the thrill of using non-approved technology at my workplace...I'm a maverick.
Just looking for the high level steps I should go through in creating an application which could be delivered to users in my team as an executable file (I have admin rights to my works laptop, but my direct reports do not have this on theirs) so would need to be able to run the app without installing if possible...
How could I read an XML document from the web? I've seen people use SAX or DOM methods, but I've unable to make them work due to lack of experience so I would need a pretty brief overview not just 2 bits of code without any imports etc.
Also how would I be able to COMPARE the information? Like if it's " Sunny " I set a label text sunny etc.?!
public class WeightedQuickUnionPathCompressionUF { private int[] id; // id[i] = parent of i private int[] sz; // sz[i] = number of objects in subtree rooted at i private int count; // number of components
[code]....
Show that, in each tree produced by the method of weighted quick unionwith or without path compression, the degree of the root (i.e., the number of its dependants) is not less than the height of the tree. I know that the height of a tree with 2^n nodes is n, however i dont know how to quantify the number of dependents in a way to use induction to prove that dependents>=height.
All I am trying to do is to make a section of code execute if two strings are equal. The two strings are userId and "A001062". When I use the debugger in Eclipse, I can see the value of userId as "A001062" but whatever string comparison I try never evaluates to true. I have tried
userId=="A001602" userId.equals("A001602") "A001602.equals(userId) Assigning A001062 to a string called AAA and comparing userId to AAA
My code is as follows. I have also attached a screen shot from the Eclipse Debugger which makes me think the string comparison should succeed. I never see the debugger execute the print line nor do I see the print line on the JBOSS console.
String userId = StringUtils.trim(nextLine[HR_USER_ID]); String AAA="A001062"; if (userId.intern().equals(AAA.intern())) {System.out.print("MKP1: " + userId+"-"+managerId);} if (userId.compareTo("DTS0428")==0) {System.out.print("MKP2: " + userId+"-"+managerId);}
I have two big text file with approx 16 Lakh (1.6 Million) records in each. Both file contains Strings in each line. I would like to compare two files and find the descripencies and print them into separate file.
I would like to create a component to detect the file being modify before process.is it the right way to detect the file modification based on file size value?
Below are the flow:
1. Get the file size of a file 2. Used file size value encrypt it with MD5 algorithm, and say it generated us encrypted value "0123sdf" 3. to avoid user modify the file content, before file process, we take the file and do the encryption with md5 again, if it return value "0123sdf", then we are sure it doesn't have modification.
my question: a. is it the right approach to detect file modification? b. what the library advise to use or using java.security.DigestInputStream will do?
I'm not so new to java i know the basics. I want to make a mastermind game. Just for training purpose.
Now i am at the comparison phase where it is comparing your chosen "colors" with the actual "color code"
This is my code for that part:
guesChars is a char array of 4 of the actual code readGuess is a string of 4 of which the players has filled in the console goodGuess is a char at the right position with the right "color" avgGues is a char with the right "color" at the wrong position
Java Code:
for(int i = 0; i < guessChars.length; i++){ for(int ii = 0; ii < readGuess.length(); ii++){ if(readGuess.charAt(ii) == guessChars[i]){ if(ii == i){

i have a folder which contains two types of files (for eg: .csv and .tiff) with same names like, abc.csv and abc.tiff.How to compare the list of files with same names while ignoring their extensions.And my second task is to copy the content from csv file and i have to use that name as file name of .tiff file(Ex: if i have a1 as content in csv file, i have to change .tiff file name from abc.tiff to a1.tiff)
java.util.Date date = new java.util.Date(); java.sql.Time cur_time = new java.sql.Time(date.getTime());
/*this is my database connectivity code from where I am getting second date that I am comparing. This is right. Don't bother it.
Connection c= ConnectionManager.getConnection(); String sql = "select t from datesheet where subjectCode=? and sessional=? and d=?"; PreparedStatement ps = c.prepareStatement(sql); ps.setString(1,subjectCode); ps.setString(2,sessional); ps.setDate(3,cur_date); ResultSet rs = ps.executeQuery();*/ if(rs.next()) { java.sql.Time t = rs.getTime("t"); long diff = cur_time.getTime()-t.getTime(); }
Then I am converting it to seconds, minutes and hours, but the problem is time that we get from cur_time.getTime() has more digits than time that we get from t.getTime(), so it is always greater than t.getTime() even when it is not.
long seconds = (diff/1000)%60; long minutes = (diff/60000)%60; long hours = (diff/(60*60*1000))%24;
I'm want to write a program to design single page documents. It needs the following features.Drag text and place it anywhere on the page, ideal I would like to add a 'snap to grid' optionDraw boxsAdd simple images (logos)
I plan to do it using Swing, but I've not done anything with this since finishing Uni. how to structure this and what swing components will be best suited for this task?
My current calculator (currently available on my site) launches your default webbrowser with the CalculatorHistory file allowing you to print through your browser, but I been working on self contain the html page in a the JEditorPane which is great it does what i want, so I started working on the printing side and I am stuck...
The code I have was from a example (modified) but when I run the code I get the following error:
Exception in thread "main" java.lang.IllegalArgumentException: services must be non-null and non-empty at javax.print.ServiceUI.printDialog(Unknown Source) at gcclinux.co.uk.PrintReport.main(PrintReport.java:28)
The Line 28 equals to PrintService service = ServiceUI.printDialog(null, 200, 200,printService, defaultService, flavor, pras);
I have created a small application for editing text using StyledDocument and JTextPane. Now, you can set the font size, font colour, and other font related stuff. My question is, how could I save this document? What is the format? When I reopen this document, all the decorations I have done to the file should be there. How do I do this?
I have task for last years in campus , how do you scan document with scanner peripheral in java program? I have browsing on internet, and I have an API like TWAIN.
