package step2; import java.lang.reflect.Field; public class ReflectFieldEdit { public static void main(String[] args) { Student student = null; // ---------------------Begin------------------------ try { Class<?> clazz = Class.forName("step2.Student"); student = (Student) clazz.newInstance(); Field nameField = clazz.getDeclaredField("name"); Field schoolField = clazz.getDeclaredField("school"); nameField.setAccessible(true); schoolField.setAccessible(true); nameField.set(student, "李四"); schoolField.set(student, "清华大学"); } catch (Exception e) { e.printStackTrace(); } // ---------------------End------------------------ System.out.println(student); } }去除这段代码输出的!

Sure! 这段代码的输出结果是一个 `Student` 对象的字符串表示，如果想要去除末尾的 `!`，只需要修改 `Student` 类的 `toString()` 方法即可。比如可以将 `toString()` 方法中的 `return` 语句改为：

return "Student [name=" + name + ", age=" + age + ", school=" + school + "]";

这样就不会有末尾的 `!` 了。
