JAVA反射获取类名，方法名，属性及构造方法

本文主要是介绍JAVA反射获取类名，方法名，属性及构造方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

//定义了个类，随便写了些属性，方法和构造方法
class ReflectTest {private String title;private int num;public String content;protected double income;public ReflectTest() {}private ReflectTest(String title, int num, double income) {this.title = title;this.num = num;this.income = income;}public ReflectTest(String title, int num) {this.title = title;this.num = num;}private void getSomeThing() {}public String getTitle() {return title;}public void setTitle(String title) {this.title = title;}public int getNum() {return num;}public void setNum(int num) {this.num = num;}public String getContent() {return content;}public void setContent(String content) {this.content = content;}public double getIncome() {return income;}public void setIncome(double income) {this.income = income;}}
