java： 一些数字到字符的转换技巧，反射访问类成员数组的方法

！本文声明：谴责烂代码 ！

接下来是正文：

关于反射访问类成员数组的方法：记住java中的数组也是对象，用Field.getObject()就行了。

本文介绍两种转换方式(在for循环里）。

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();
}
}
