listFiles() bug?
Feb 16th, 2010, 9:38am  
Hi,

I am trying to do string comparisons on lists of files. I found this to be a problem so I reduced it to this. Fill in the name of the file you are looking for in y and then pathtoafile is the system path to the file. When you first run the program copy and paste the string printed in the output to string y and it won't come back as true.

When I do simple string comparison I get a true but the string that is returned and printed from File.listFiles() doesn't seem to be equivalent. Any help is appreciated.


String y = "somefile.jpg ";
String pathtoafile = "/FILL/IN/THE/PATH/HERE";

File pathtoimages = new File(pathtoafile);
File[] files = pathtoimages.listFiles();

println(files[1].getName());

if (y == files[1].getName())
println("true");

You should read attentively the String reference before suspecting a bug in Java... Smiley

Hint: don't use == to compare strings.
