How do EL Expression containing combination Arithmetic ,Logical, Relational Operators work ?

[Mohit G Gupta]

<% int[] nums = {42,420,4200}; request.setAttribute("foo", nums); %> ${5 + 3 lt 6} ${requestScope['foo'][0] ne 10 div 0} {0 div 0} ${requestScope['foo'][0] ne 10 } ${10 div 0} ${not myBean.testproperty > 35 && myBean.testproperty < 25}<%--Attempt to coerce a value of type "java.lang.Integer" to Boolean-->

myBean is a bean created in request scope with value of testproperty as 33

I am unable to get How these El expression operate.

How to EL operator work left to right or viceversa if in an EL we have combination of Arithmetic ,Logical and Relational operators ?

The same way you expect them to work in java code. The operator precedence is same as in java.

For example: ${5 + 3 lt 6} will work same way as: (5 + 3 < 6) in a java code.
