Boolean Method Problem

[Olivier Legat]

Hello everyone,

I got this method which is meant to check if a name exists or not in a Random Access File. Basically, before I add an extra, I need to run this method to make sure that that line doesn't already exist somewhere else in the file. But no matter what happens it ALWAYS returns false

Here's the code:

    
public static boolean duplicateCheck(RandomAccessFile raf, String Name)
{
boolean duplicate = false;
boolean done = false;
try{
raf.seek(0);
while(!duplicate && !done)
{
String dupCheck = raf.readLine();
if(dupCheck.equalsIgnoreCase(Name))
{duplicate = true;}

else if(raf.getFilePointer() == raf.length())
{done = true;}
}
}
catch(Exception e){}

return duplicate;
}

Any ideas why this is happening?

if the file is not too big, try putting in some print statements to see what the strings are it's comparing at each step. I usually do something like

system.out.println("|" + myString + "|");

the pipes let me know EXACTLY where the string starts/ends in case there is whitespace on the beginning or end i may not see otherwise.
