Commons Lang、ClassUtils.convertClassesToClassNames()

import org.apache.commons.lang.ClassUtils;
import java.util.*;

public class C2009081600 {
    public static void main(String[] args) {
        LinkedList ll = new LinkedList();
        ll.add(String.class);
        ll.add(Integer.class);

        List list = ClassUtils.convertClassesToClassNames(ll);
        Iterator iter = list.iterator();
        while (iter.hasNext()) {
            System.out.println((String)iter.next());
        }
    }
}

で、

java.lang.String
java.lang.Integer

import org.apache.commons.lang.ClassUtils;
import java.util.*;

public class C2009081601 {
    public static void main(String[] args) {
        LinkedList ll = new LinkedList();
        ll.add(String.class);
        ll.add(Integer.class);

        for (Object o : ClassUtils.convertClassesToClassNames(ll)) {
            System.out.println((String)o);
        }
    }
}

で、

java.lang.String
java.lang.Integer
