Hi, i am facing a problem with reading of duplicate element in an array. I was told to ignore the duplicate element in a text file and continue read in data from the text file at the same time store the data in an object array and diaplay it. However, i could only perform a boolean checking and not ignore the duplicate element.Can anyone help? May i know what should i do to solve my problem? Below is the attachment of my code and text file. Thank in advance=D
For below text file i must continue read in id: 123, 126, 65, 78, 655 and ignore the 655 duplicate record. In other words, i should read in five records instead of six.
textfile.txt

//check existence of duplicate Account ID

}
}

while ((line1 = br.readLine()) != null) {

while (st2.hasMoreTokens()) {
data = st2.nextToken();
if (data.equals("Account Id ")) {

}
}

System.out.println("Number of record " +

} catch (FileNotFoundException ex) {

} else if (duplicate == true) {

}
br.close();
