用Java打印中文字符的GBK，UTF8和UTF16编码

package unicode;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
public class unicodeTest {
  public static void main(String[] args) {
    String shang = "殇";
    String result = "";
    System.out.println(shang);
    try {
      result = URLEncoder.encode(shang, "GBK");
      System.out.println("GBK:" + result);
        result = URLEncoder.encode(shang, "UTF-8");
      System.out.println("UTF8: " + result);
      result = URLEncoder.encode(shang, "UTF-16");
      System.out.println("UTF16:" + result);
    } catch (UnsupportedEncodingException e) {
      e.printStackTrace();
    }
  }
}
