SE452: JSP Expression Language - capabilities [7/18]

The JSP EL has the following capabilities:

• access to store objects - instead of jsp:useBean, you can access an object in any scope just using its name: ${beanName}
• bean properties - you can access the properties of a bean using shorthand as well: ${beanName.property}
• collections - you can access indexed arrays, Lists, Maps using shorthand notation as well: ${elements[5]}
• request data - you can get to request data quickly using shorthand: ${header["User-Agent"]}
• conditional output - don't have to resort to scriptlets: ${test ? option1 : option2}
• type conversion - converts most string and number typecasts done logically.
• null - treats null as "" in most cases
