import org.languagetool.tokenizers.
;
import org.languagetool.language.*;

public class Main {
private final JLanguageTool langTool = new JLanguageTool(new Ukrainian());

private void check(String text) throws Exception {

List matches = langTool.check(text);
for (RuleMatch match : matches) {
System.out.println("Possible error: " +
match.getLine() + ", column " +
match.getColumn() + ": " + match.getMessage());
System.out.println("Suggestions: " + match.getSuggestedReplacements());
}
}

public static void main(String[] args) throws Exception {
System.out.println(“Running simple client program”);
