HTTP Status 500 - For input string: "3.0"

我在做一个增加数据功能的网页，测试时出现了错误提示如下（输入整型数据时不报错，但是输入浮点型数据时却报错）：
java.lang.NumberFormatException: For input string: "2.0"
java.lang.NumberFormatException.forInputString(Unknown Source)
java.lang.Integer.parseInt(Unknown Source)
java.lang.Integer.parseInt(Unknown Source)
example4.Insert.doPost(Insert.java:31)
javax.servlet.http.HttpServlet.service(HttpServlet.java:650)
javax.servlet.http.HttpServlet.service(HttpServlet.java:731)
org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

note The full stack trace of the root cause is available in the Apache Tomcat/7.0.68 logs.
相关代码如下：
view界面代码：


X：
Y：

javabean代码：
//获取前台页面数据
String x3 =request.getParameter("x");

    double x = Double.parseDouble(x3); 

    String y1 =request.getParameter("y");

    double y = Double.parseDouble(y1); 

    我是新手，请各位大神帮我诊断一下，感激不尽！
