Surround Text In JTextFiled With Quotes

After opening a file dialog box and choosing a file and the path to that file is placed ina jTextField, How can I surround that text with quotes, if that path contains spaces? This is how I did it in VB.

Function WrapIfRequired(ByVal Filename As String) As String
Dim containsSpaces As Boolean = False
Dim FilePath As String = Filename.Trim
If FilePath.Contains(" ") Then containsSpaces = True
If containsSpaces = True Then
Return """" & FilePath & """"
Else
Return FilePath
End If
