java： 一些數字到字符的轉換技巧，反射訪問類成員數組的方法

 ！本文聲明：譴責爛代碼 ！ 

接下來是正文：

關於反射訪問類成員數組的方法：記住java中的數組也是對象，用Field.getObject()就行了。

本文介紹兩種轉換方式(在for循環裏）。

import java.io.IOException;
import java.io.StringWriter;
import java.lang.reflect.Field;

public class Converter {
    public static void main(String[] args) throws IOException, IllegalArgumentException,
            IllegalAccessException {
        NumberSet numSet = new NumberSet();
        Field[] fields = NumberSet.class.getDeclaredFields();
        for (Field f : fields) {
            System.out.println(f.getName() + ":" + f.getType());

            if ("class [I".equals(f.getType().toString())) {
                int[] is = (int[]) f.get(numSet);
                // for (int i : is) {
                // System.out.print(i);   //no
                // }
                StringWriter writer = new StringWriter();
                writer.write(numSet.Animals);
                writer.flush();
                StringBuffer sb = writer.getBuffer();
                System.out.print(sb);
                writer.close();
            } else if ("class [C".equals(f.getType().toString())) {
                char[] cs = (char[]) f.get(numSet);
                for (char c : cs) {
                    System.out.print(c);
                }
            }
            System.out.println();

        }

        StringWriter writer = new StringWriter();
        writer.write(numSet.Animals);
        writer.flush();
        StringBuffer sb = writer.getBuffer();
        System.out.println(sb);
        writer.close();
    }
