What are the similarities and differences between JSP and Servlet, and what is the connection between them?

Differences and linkages between JSPS and servlets:
1.jsp is compiled into a servlet. (the essence of JSP is that SERVLET,JVM can only recognize Java classes, not the code of the jsp, the Web container compiles the JSP code into the Java class that the JVM can Recognize)
2.jsp is better at displaying pages, and servlets are better at logic Control.
There are no built-in objects in 3.Servlet, the built-in objects in the JSP must be obtained by HttpServletRequest objects, httpservletresponse objects, and HttpServlet Objects.
JSP is a simplification of servlets, the use of JSP only need to complete the programmer needs to output to the Client's content, JSP java script How to mosaic into a class, by the JSP container to Complete. The servlet is a complete Java class, and the service method of this class is used to generate a response to the Client.
Contact:  JSP is an extension of servlet technology, which is essentially a simple way for servlets. The JSP is compiled with a "class servlet". The main difference between Servlets and JSPs is that the application logic of the servlet is in the Java file and is completely detached from the HTML in the presentation Layer. The case for JSP is that Java and HTML can be combined into a file with A. jsp Extension. JSP focuses on views, and servlets are used primarily for control logic
