Assuming what you provided is an example of what you want to do in your JSP, the easiest way to do what you are tying to do is to use a JSTL forEach.
假设您提供的是您想要在 JSP 中执行的操作的示例，那么执行您要执行的操作的最简单方法是使用JSTL forEach。
<c:forEach items="${yourArray}" var="myItem" varStatus="myItemStat">
yourArray[${myItemStat.index}] = ${myItem}
</c:forEach>
This assumes you have passed your "yourArray" to the JSP. There are LOTS of tutorials on how to do all of this sprinkled all over the Internet.
这假设您已将“yourArray”传递给 JSP。互联网上散布着大量关于如何完成所有这些工作的教程。

In jsp page you can use this:
在jsp页面中你可以使用这个：
<%
while(rs.next()){
count++;
anArray[i]=rs.getString("subject");
out.println(anArray[i]);
i++;
}
while(rs1.next()){
anArray[i]=rs1.getString("subject");
out.println(anArray[i]);
i++;
}
%>

As i understand your, you are making the output in console , and you are trying to print it in browser.
据我了解，您正在控制台中进行输出，并尝试在浏览器中打印它。
To get the output in browser
在浏览器中获取输出
Just importthe java class in JSPpage
只是页面中import的java类JSP
In JSP page between tag(<%..%>) by java class object print it in browser,
在 JSP 页面之间的 tag(<%..%>) 由 java 类对象打印在浏览器中，
<%@page import="pack.sample"%>
<%
//In scriplets
Sample obj=new Sample();
String str[]=obj.printMe();//Here printMe() is a fn from Sample class which will return string array
//Now here do all stuffs with str[]
//out.println(str[0]);//It will return zeroth value of str[] in your browser
%>
