Error: "The method startsWith(String, String) is undefined for the type StringUtils"

[shihad_s]

Hii,

I got an error during compiling the below line: Error: "The method startsWith(String, String) is undefined for the type StringUtils"

code: if (StringUtils.isBlank (line) || StringUtils.startsWith (line, "#"))

I have imported all the required packages ( import org.apache.commons.lang.StringUtils; ..) and jars..

Please anyone let me know what the error was..

Thanks

The compiler already told you: the class StringUtils doesn't have a method startsWith( ... ); check the documentation.

Thanks josAH for your reply.....
But class "StringUtils" have the method startsWith(string, string) I have checked and confirmed that..

Hi josAH,

Just check this link. It specifies the method startsWith(string, string) in the class StringUtils

Yes, I read it already; have you correctly imported the package or class?

Hi josAH,

Error is solved. i tried Mr. SmilingKey's suggestion..: " line.startsWith("#") ". Now it is working.. Thanks for all your replies. Expecting your co-operation in the future also..

You 'unsolved' the problem: the String class also has a startsWith( ... ) method but now we still don't know why your original attempt didn't work; the StringUtil class also seems to implement a (static) startsWith( ... ) method.

Ya, thats right.. My actual code is given below:

-----------------------------------------------------------

private List<String> loadTestValues (String _resourceName) throws IOException
{
final InputStream testFileStream = getClass ().getClassLoader ().getResourceAsStream (_resourceName);
List<String> lines;
try
{
assertNotNull ("unable to find " + _resourceName, testFileStream);
lines = IOUtils.readLines (testFileStream);
}
finally
{
IOUtils.closeQuietly (testFileStream);
}
final Iterator<String> i = lines.iterator ();
while (i.hasNext ())
{
final String line = i.next ();

if (StringUtils.isBlank (line) || StringUtils.startsWith (line, "#"))
{
i.remove ();
}
}
return lines;
}

-------------------------------------------------------------------------

Line marked in bold causes the error: "The method startsWith(String, String) is undefined for the type StringUtils". I dnt Know why the error is happening. I have imported all required packages and jar's.. Can you please try to find out that..

write "StringUtils." in you code to see if StringUtils you are using has method startsWith (String, String).

If not, you can use:
if (StringUtils.isBlank (line) || line.startsWith ("#"))
