A DESCRIPTION OF THE PROBLEM :
Under the "showOpenDialog" function documentation, under "Returns:", the pages says that showOpenDialog() can return "JFileCHooser.ERROR_OPTION". This looks like a typo to me.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
JFileChooser.ERROR_OPTION
ACTUAL -
JFileCHooser.ERROR_OPTION
