java.util.array not recognised

[apeksha agarwal]

hi everyone..
my problem is that during import of util.array.* in order to use asList function my system is not recognizing util.array as well as asList..
please tell me how to resolve such a problem.

thank you.

[Bear Bibeault]

Spell it correctly.

[apeksha agarwal]

sir even after spelling it correctly its not recognizing asList function.

[Bear Bibeault]

Don't tell us. Show us.

import java.util.*;
import java.lang.*;
import org.annolab.tt4j.*;
import static org.annolab.tt4j.Util.join;
public class tagging {
	public static void main(String[] args) {
	System.setProperty("treetagger.home", "c://treetagger");
	 TreeTaggerWrapper tt = new TreeTaggerWrapper<String>();
	 try {
	     tt.setModel("/c:/treetagger/models/english.par:iso8859-1");
	     tt.setHandler(new TokenHandler<String>() {
	         public void token(String token, String pos, String lemma) {
	             System.out.println(token+"\t"+pos+"\t"+lemma);
	         }
	     });
	  
         tt.process(asList(new String[] {"This", "is", "a", "test", "."}));
	 }
	 finally {
	     tt.destroy();
	 }
	
	}

}

sir above is my code and the bold line indicates the line in which i am having problem.
below is the process method given in which asList is used.

public
void process(
		final Collection<O> aTokenList)
throws IOException, TreeTaggerException // This line was bold
{
	// In normal more sort out all tokens that we cannot handle. In
	// particular line breaks and tabs cannot be handled by TreeTagger.
	Collection<O> aTokens;
	if (!_performanceMode) {
		aTokens = removeProblematicTokens(aTokenList);
	}
	else {
		aTokens = aTokenList;
	}

	// Remember the number of tokens we originally got.
	_numTokens = aTokens.size();
	_tokensRead = 0;
	_tokensWritten = 0;
	_lastTokenRead = null;
	_lastTokenReadTT = null;
	_lastTokenWritten = null;

	final Process taggerProc = getTaggerProcess();

	// One thread reads the output.
	final Reader reader = new Reader(
			taggerProc.getInputStream(), aTokens.iterator());
	final Thread readerThread = new Thread(reader);
	readerThread.start();

	// One thread consumes stderr so we do not get a deadlock.
	final StreamGobbler gob = new StreamGobbler(taggerProc.getErrorStream());
	new Thread(gob).start();

	// Now we can start writing.
	final Writer writer = new Writer(aTokens.iterator());
	new Thread(writer).start();

	// Wait for the processing to end. Every once in a while we check if an
	// exception has been thrown. When the Reader thread is complete, we can
	// stop.
	try {
		// Wait for the Reader thread to end.
		synchronized (reader) {
			while (readerThread.getState() != State.TERMINATED) {
				try {
					// If the reader or writer fail, we kill the treetagger and bail
					// out. This may be a bit harsh, but easier than coding the
					// Reader and Writer so that we can abort them. If the process
					// is dead, the streams die and then the threads will also die
					// with an IOException.
					if (writer.getException() != null) {
						destroy();
						throw new TreeTaggerException(writer.getException());
					}

					if (reader.getException() != null) {
						destroy();
						throw new TreeTaggerException(reader.getException());
					}

					reader.wait(20);
				}
				catch (final InterruptedException e) {
					// Ignore
				}
			}
		}
	}
	finally {
		gob.done();
	}

//	info("Parsed " + count + " pos segments");
}

So your "tagging" class doesn't have an asList() method, and the compiler tells you so. (Correct? Post the actual compiler error message if you don't agree with that.) This has nothing to do with asList() methods that you found in some other class.

[apeksha agarwal]

yes sir..
error is "method asList(String[]) is undefined for the type tagging"

[Paul Clapham]

Okay. So did you plan to write your own asList() method for that class? Or did you mean to use the static method from the Arrays class?

[apeksha agarwal]

sir, i am planing to use the static method from the from the arrays class..

[Campbell Ritchie]

And what are you trying to import? Are you trying to import a static method? Where it says typeName, it means the full-qualified name of the class/interface.
Please use the Java™ conventions: spaces for indenting, not tabs, capital letters for class names, names do not start with _ (except package names). Since you are new, I have added code tags and you can see how much better your code looks.
What are you calling a destroy() method on?

And welcome to the Ranch

[apeksha agarwal]

thanks..

well i am trying to import the util.Arrays.
but still its not recognizing asList..

[Paul Clapham]

Okay. Let's see the import statement you have now, then.
