mecabで名詞の数を数える

tfidfで必要な名詞の数を数えるプログラムが出来上がりましたよ――☆

import net.moraleboost.mecab.Tagger;
import net.moraleboost.mecab.Node;
//import net.moraleboost.mecab.TaggerTest;

public class test3{
public static void main(String args) throws Exception
{
System.out.println("MeCab version: " + Tagger.version());
System.out.println();
String text = "今日は暑いです";
System.out.println("Original text: " + text);
System.out.println();
System.out.println("解析");
Tagger tagger = new Tagger("UTF-8", "");
Node node = tagger.parse(text);

//while (node.hasNext()) {
String surface = new String[10];
String feature = new String[10];

for(int i=0; i<10 ; i++){
surface[i] = node.next();
feature[i] = node.feature();

//surface[1] = node.next();
//feature[1] = node.feature();

System.out.println(surface[i] +"\t"+ feature[i]);

}
int hz =0;
for(int i=0;i<10;i++){
String fruit = feature[i].split(",", 0);
if(fruit[0].equals("名詞")){
System.out.println(surface[i]);
hz = hz+1;

}

}
System.out.println(hz);

}
}
