<%@ page language="java" import="java.util.*"  %>
<%@ page pageEncoding="UTF-8" isELIgnored="false" %>
<%@ page import="java.util.Date" %>
<html>
  <head> 
    <title>  </title>
  </head>  
  <body>
     <h1> Present time: </h1>
     <%=new Date() %>
  </body>
</html>

The servlet generated after translation has the following code in the corresponding body:


out.write("<h1> Present time: </h1>n");
out.print( new Date());

There is a method: print(Object), there is no method: write(Object)
But it has this method: write(String)
Look up the javaAPI and you'll find it.
Conclusion:
Out.print () method, which outputs a Java object;
Out.write () method, which can enter only one string.
