Focus on the use of the three-mesh operator.

JSP is primarily responsible for showing that all complex business operations are given to the servlet to complete.

Calculation operator: +,-, *,/,% (modulo)

<%@ page contenttype= "text/html" pageencoding= "GBK"%>//  storage is digital    Pagecontext.setattribute ("NUM1");    Pagecontext.setattribute ("num2", +); %>

Judgment operator: Equals (eq), unequal (NE), less than (LT), greater than (GT), less than or equal (LE), greater than or equal (GE)

<%@ page contenttype= "text/html" pageencoding= "GBK"%>//  storage is digital    Pagecontext.setattribute ("NUM1");    Pagecontext.setattribute ("num2", +); %>

Logical operators: &&=and, | | =or,!=not

<%@ page contenttype= "text/html" pageencoding= "GBK"%>//  storage is digital    Pagecontext.setattribute ("Flaga",true);    Pagecontext.setattribute ("FLAGB",false); %>

The three-mesh operator is the most important: num1>num2? "Greater than": "Less than"

<%@ page contenttype= "text/html" pageencoding= "GBK"%>//  storage is digital    Pagecontext.setattribute ("Num1", ten);    Pagecontext.setattribute ("num2");    Pagecontext.setattribute ("num3", +); %>
