How to Compare Two Strng without .equals() method

Hiii,
How to compare two Strings with out .equals method if there are white spaces in between these string it should be avoided..
eg: ab cd ef g is equal to a bc de fg
Please give me the logic or code..
Your help will be appreciated

dude find the code without the equal method
public class test {

          String str1 = "a bc de fg";
          char []ch = str.toCharArray();
          char []ch1 = str1.toCharArray();
          int counter =0, counter1 = 0;
          while(counter < ch.length && counter1 < ch1.length)
               while(ch[counter]==' ')
                    counter++;
               while(ch1[counter1]==' ')
                    counter1++;
               if(ch[counter] != ch1[counter1])
                    break;
               counter++; counter1++;
          if(counter == ch.length && counter1 == ch1.length)
               System.out.println("true");
          else
               System.out.println("false");

  • How to compare two databases, without dblink?

    Hi all,
    I need to compare two differents databases, but I can't create a database link, and for make this task worse, I need to do this using a shell script, because it will run directly in the server.
    Anybody can help me?

    Hi Justin,
    I made the script, and it was working pretty well, but when I was running in the production environment, I get the information that I need to connect with one user and get the ddl to another user, ok, I change the script but now I'm receving the error ORA-31603.

    I took a look on the internet and metalink, and saw some notes about grant SELECT_CATALOG_ROLE to the connect user, but I can't do this in my customer.

  • ??how to compare two resultsets??

    hi all!
    i need to find out whether two resultsets contain the same data.
    the only way i know how to do it in java is to put them into a while loop and fetch the contents first and then compare the contents.
    but is there an easier way to compare resultsets?
    does anyone know how to compare two resultsets without extracting the data?
    the code example here executes two identical queries on an oracle database, compare and print the resultsets.
    public ResultSet getResultset(String query)
    ResultSet rs=null;
    try { rs=Stmt.executeQuery(query); }
    catch(Exception e) { e.printStackTrace(); }
    return rs;
    public static void main(String[] args) {
    ResultSet r1=null;
    ResultSet r2=null;
    try {
    database db = new ddatabase();
    r1=db.getResultset("Select 'name' from person");
    r2=db.getResultset("Select 'name' from person");
    if (r1 == r2) {
    System.out.println("ok");
    System.out.print(r1);
    System.out.println();
    System.out.print(r2);
    else {
    System.out.println("not ok");
    System.out.print(r1);
    System.out.println();
    System.out.print(r2);
    jdbc.cleanup();
    catch(Exception e) {e.printStackTrace();}
    and here is the output:
    F:\java rs_compare
    not ok
    oracle.jdbc.driver.OracleResultSetImpl@4413ee
    oracle.jdbc.driver.OracleResultSetImpl@786e64
    as you can see the resultsets are different though the data they contain have to be the same.
    so the 'if(resultset#1 == resultset#2)' does not work.
    thanks for any help
    best regards

    Don't cross-post.
    I'll bet ResultSet implementations don't override equals() to provide "deep equals" behavior, in which case it'll be no different than using "==".
    It's a bad idea to compare two ResultSets this way. You'll have to load both into objects or data structures and compare those in a "deep" way.
    Besides, the ONLY way two ResultSets could be different, given the same query, would be if there were multiple clients that could write to the table between queries and change the underlying data. If your two queries are sufficiently isolated, I'd say that the same query will return the same ResultSet.

  • How to compare two strings whether both are equal while ignoring the difference in special characters (example: & vs & and many others)?

    I attempted to compare two strings whether they are equal or not. They should return true if both are equal.
    One string is based on Taxonomy's Term (i.e. Term.Name) whereas other string is based on String object.
    The problem is that both strings which seem equal return false instead of true. Both string values have different special characters though their special characters are & and &
    Snapshot of different design & same symbols:
    Is it due to different culture or language?
    How to compare two strings whether both are equal while ignoring the difference in special characters (& vs &)?

    Hi Jerioon,
    If you have a list of possible ambiguous characters the job is going to be easy and if (& vs &) are the only charracters in concern awesome.
    You can use the below solution.
    Before comparing pass the variables through a replace function to standarize the char set.
    $Var = Replace($Var,"&","&")
    This is going to make sure you don't end up with ambiguous characters failing the comparison and all the char are "&" in this case.
    Similar technique is used to ignore Character Cases 'a' vs. 'A'

  • How to compare two Objects !!!!

    Hi All,
    I know that this question has been asked 100 times till now. But trust me I have checked all of them but couldn`t find answer. Here is my question:
    I have an objecs. In that object I am setting (Id,Name,DOJ). Now I want to check whether the object I am trying to save in database already exists or not. If exists then I need to check whether all the setters are same for the two objects. Now can anyone tell me ,how to compare two objects directly without comparing the setters individually.
    Thanks in advance.

    pavan13 wrote:
    That is pretty good idea. However I have a query. Does that code actually compare all the setters in a two beans. I don`t want to check each setter seperately.Well, it's pretty meaningless to talk about "comparing setters", setters are methods, they don't have values to compare. Because equals is inside the class, you can simply compare the fields that get set by the setters. "Properties" is probably a better name.
    In principal you could write something that tried to find all relevant fields and compare them, using reflection or bean info stuff. The resulting code would be about 50 times longer and take about 50 times longer to run. It's hardly asking a lot to put three comparisons between && operators.
    Remember, though, not to compare string fields with ==, you should call .equals on the string fields.
    p.s. don't let the bean terminology confuse you. Beans are just ordinary objects which follow a few rules. Personally I wish the term had never been coined.

  • How to compare two files using MD5?

    Hi,all:
    How to compare two files to know if they're the same without any difference?I want to use MD5, but I just konw how get a message digest of a string. How to get a message digest of a file? Or there is other method to compare two files?
    Thanks advance!

    This is starting to sound rather a lot like a homework problem.
    An MD5 message digest is simply a 16 byte array. To compare two message digests...
    byte[] md5incoming = ...
    byte[] md5comparison = ...
    if( md5incoming.equals(md5comparison) ) {
       System.out.println("MD5 Checksums match");
    }To find out how to generate an MD5 checksum, please look up MessageDigest in the API documentation, and do a google search for "MD5 java"
    In a networked scenario, there are two issues - firstly the performance in sending copies of files all over the place (imagine if it's a 10Gb file to be compared over a 14.4K modem link, this would take a while). Secondly, the network link itself might insert an error in the file and you'd get a false miss.
    By only sending MD5 digests over the link, you simultaneously reduce the error (shorter files are less likely to be corrupted) and reduce the transmission time (16 bytes takes practically no time to transmit over damp string, let alone any sort of sensible device).

    Harsha

    Hi Harsha,
    Transaction WE05 will help you out.You should first know some details like the
    iDoc type, partner, the date/time and maybe the iDoc #. There can be many iDocs
    generated/processed per day and without having some info to start with,
    one will never find anything useful. Filter what you can, and then
    navigate in the left hand frame/double click on the results lines in the
    right hand frame to drill down. Eventually you will see the single iDoc
    with all the many 'segments' available. Expand the 'data records'
    branch (and sub-branches) to see each 'segment' and find the data fields
    & values (these will appear in the lower right hand frame).
    Reward points if helpful..
