How to compare content of two text file using StreamTokenizer

hi....
i have two text files...containg field like(name,number,scheme) and(number,date,value)... i want to create a third file containg field like (name,number,date,scheme,value) by using these two table. how to create

I think this code can solve your problem.
private static final String DELIM = ",";
* Compile two files.
* @param file1 String the input file 1
* @param file2 String the input file 2
* @param file3 String the output file
* @throws IOException error in reading/writing
public void compileFiles(String file1, String file2, String file3) throws
        IOException {
        BufferedReader reader1 = new BufferedReader(new InputStreamReader(
            new FileInputStream(file1)));
        BufferedReader reader2 = new BufferedReader(new InputStreamReader(
            new FileInputStream(file2)));
        BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(
            new FileOutputStream(file3)));
        String line1 = reader1.readLine();
        String line2 = reader2.readLine();
        while (line1 != null && line2 != null) {
            writer.write(compileLines(line1, line2));
            writer.newLine();
            line1 = reader1.readLine();
            line2 = reader2.readLine();
        reader1.close();
        reader2.close();
        writer.close();
    private String compileLines(String line1, String line2) {
        StringTokenizer tok1 = new StringTokenizer(line1, DELIM);
        StringTokenizer tok2 = new StringTokenizer(line2, DELIM);
        String name = tok1.nextToken();
        String number = tok1.nextToken();
        String scheme = tok1.nextToken();
        // ignore number
        tok2.nextToken();
        String date = tok2.nextToken();
        String value = tok2.nextToken();
        StringBuffer buffer = new StringBuffer();
        buffer.append(name);
        buffer.append(DELIM);
        buffer.append(number);
        buffer.append(DELIM);

  • Comparing contents of two text files

    I know that I can copy all contents of the two files into two strings, and then do str1.equals(str2). Any better way to do it?

    What kind of comparison do you want to do?
    - Exact - the files must have the same size, and have the same bytes, like "fc /b" in Windows
    The exact comparison is very easy to do: open the files as FileInputStreams and read both using byte buffers. Compare the byte buffers.
    If you can't open both files at the same time (for instance, one of the files is in a diskette and the other file is in another diskette, and you have only one diskette drive) you could try checking the digest of the files (java.security.MessageDigest). If the digest values match, probably the files are equal. If the digest values don't match, certainly the files are different.
    - Textual - you want to find differences between the files, and pinpoint them, like the "diff" command in Unix, or the "fc" command in Windows.
    Textual comparison is not easy to do (you'll need to keep lists of matching lines, and figure out if some sequence of lines was moved, changed etc.); but you can find the source code for it in several places.

  • How to convert content of a Text file to String?

    Hi,
    I need to read the content of a text file and convert it into String and display it on to a JSP file.
    But the codings below don't work. Please advise me on how can i display the text file content.
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    File adCheck = new File("list.txt");
    fis = new FileInputStream(adCheck);
    int Length = adCheck.length();
    byte arr[] = new byte[Length];

         totalData += dataRead;
    String Content = new String(arr);//byte array converted to String
    arr = null;

    Take a BufferReader:
    BufferedReader read = new BufferedReader(new FileReader("c:\test.txt");
    String temp = read.readln();
    You can make loops etc. Adding new Strings to an ArrayList,
    adding Strings etc....

  • How to compare and edit Resource bundle file using java programe

    Hi All
    I have two resource bundle with key, value and some comments. I need to write a java code to compare both of the values of the keys and if the values are different then i want to replace the second value with the first value.
    Its a programe which will udpate the second file with the first file values.
    I tried using Properties class but it didnt worked because when i am saving the file using store method it removes all the comments and the order of text also got disturbed.
    How I need to do this any help appriciated.
    Please elt me know if someone needs more info.
    Thanks in advance.

    Let's assume the ini file is a mapping type storage (key=value) so lets use Properties object. (works with java 1.4 & up)
    import java.io.File;
    import java.io.FileInputStream;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.util.Properties;
    public class Test {
         private static Properties props;
         public static void main(String[] args) throws IOException {
              File file = new File("test.ini");//This is out ini file
              props = new Properties();//Create the properties object
              read(file);//Read the ini file
              //Once we've populated the Properties object. set/add a property using the setProperty() method.
              props.setProperty("testing", "value");
              write(file);//Write to ini file
         public static void read(File file) throws IOException {
              FileInputStream fis = new FileInputStream(file);//Create a FileInputStream
              props.load(fis);//load the ini to the Properties file
              fis.close();//close
         public static void write(File file) throws IOException {
              FileOutputStream fos = new FileOutputStream(file);//Create a FileOutputStream
              props.store(fos, "");//write the Properties object values to our ini file

  • Compare two text files in Powershell and if a name is found in both files output content from file 2 to a 3rd text file

    Is it possible using PowerShell to compare the contents of two text files line by line and if a line is found output that line to a third text file?
    Lets say hypothetically someone asks us to search a text file named names1.txt and when a name is found in names1.txt we then pair that with the same name in the second text file called names2.txt
    lets say the names shown below are in names1.txt
    Bob
    Mike
    George
    Lets say the names and contents shown below are in names2.txt
    Lisa
    Jordan
    Mike 1112222
    Bob 8675309
    Don
    Joe
    Lets say we want names3.txt to contain the data shown below
    Mike 1112222
    Bob 8675309
    In vbscript I used search and replace commands to get part of the way there like this
    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objFile = objFSO.OpenTextFile("testing.txt", ForReading)
    strText = objFile.ReadAll
    objFile.Close
    strNewText = Replace(strText, "Mike ", "Mike 1112222")
    Set objFile = objFSO.OpenTextFile("testing.txt", ForWriting)
    objFile.WriteLine strNewText
    objFile.Close
    That script works great when you know the name you are looking for and the correct values. Lets say someone gives you a list of 1000 employees and says import these names into a list in the correct format and one sheet has the correct names only and
    the other sheet has lots of extra names say 200000 and you only need the 1000 you are looking for in the format from names2.txt.

    Sure,
    Here's a simple one:
    $names1 = "C:\names1.txt"
    $names2 = "C:\names2.txt"
    $names3 = "C:\names3.txt"
    Get-Content $names1 | ForEach-Object {
    $names1_Line = $_
    Get-Content $names2 | Where-Object {$_.Contains($names1_Line)} | Out-File -FilePath $names3 -Append
    This basically just reads $names1 file, line by line, and then read $names2 file line by line as well.
    If the line being evaluated from $names2 file contains the line being evaluated from $names1 file, then the line from $names2 file gets output to $names3 file, appending to what's already there.
    This might need a few more tinkering to get it to perform faster etc depending on your requirements. For example:
    - If either $names1 or $names2 contain a lot of entries (in the region of hundreds) then it will be faster to load the whole content of $names2 into memory rather than opening the file, reading line by line, closing and then doing the same for every single
    line in $names1 (which is how it is currently works)
    - Make sure that your comparison is behaving as expected. The .Contains method always does a case sensitive comparison, this might not be what you are after.
    - You might want to put a condition to ignore blank lines or lines with spaces, else they'll also be brought over to $names3
    Hopefully this will get you started though and ask if you have further questions.

  • Comparing two text files in a UNIX using shell programming

    Hi All,
    Sorry for posting a UNIX shell query on Database forums.
    I want to compare two text files using shell programming. The two text files are actually Business Objects output extracted in a text format. The two output files are not in a tabular format and are no way similar in looking. I want to take one file e.g. file1 as an input file and compare each line of file1 with the other file e.g. file2. During comparison I want to extract the differences found in another file and if possible the similar data as well.

    As you can see above the file are not at all matching except for one record UHL1, but its just an example. As an output I would like to have a third file containing all these records, highlighting the differences, and a fourth file where in only the matched records should get populated.
    Please post any useful scripts related to the above scenario.
    Many Thanks.

  • How to store the contents of a text file directly in to a clob field

    Hi All,
    Could anyone help me to store the contents of a text file (*.txt,*.xml etc)directly in to a clob field.
    Thanks in advance
    Jayaram.

    One way is to use sqlloader. Three files are used. A control file, an xml data file, and a file with the path of the xml data file. Here's the control file. It reads load.file, which is the file with the path of the xml data file. It names the path ext_path, and inserts the xml into field xml_field.
    CONTENTS OF CONTROL FILE:
    load DATA
    INFILE 'load.file'
    APPEND
    INTO TABLE xml_table
    ( ext_path FILLER CHAR(13),
    "XML_FIELD" LOBFILE(ext_fname) TERMINATED BY EOF
    CONTENTS OF FILE LOAD.FILE:
    /tmp/load.dat
    The xml is in the file /tmp/load.dat.
    null
