求个全代码

Answer 1

package cn;
import java.lang.reflect.*;
public class Test {
private double d;
public static final int i = 37;
String s = "testing";
public static void main(String args[]) {
try {
Class cls = Class.forName("cn.Test");
Field fieldlist[] = cls.getDeclaredFields();
for (int i = 0; i < fieldlist.length; i++) {
Field fld = fieldlist[i];
System.out.println("name = " + fld.getName());
System.out.println("decl class = " + fld.getDeclaringClass());
System.out.println("type = " + fld.getType());
int mod = fld.getModifiers();
System.out.println("modifiers = " + Modifier.toString(mod));
System.out.println("-----");
}
} catch (Throwable e) {
System.err.println(e);
}
}
}

Answer 2

看看API文档的Class类、Field类的用法。比较简单的。
