Comparison operators

When applied to primitive data types, the comparison operators return a value of type boolean.

== equal to   (Attention: = is different from == )
!= different from
> greater than
< less than
>= greater than or equal to
<= less than or equal to

Example:
10 < 20 is a boolean expression equivalent to true
10 == 20 is a boolean expression equivalent to false
10 != 20 is a boolean expression equivalent to true

Example:

boolean x = 10 < 20;     // assignment of the value of a boolean expression
System.out.println(x);   // prints "true"
