1Z0-811 Primitives, Strings and Operators Practice Question
Which THREE of the following expressions evaluate to true? (Assume int a=5, b=10)
⚠ Common exam trap
Oracle often tests the distinction between assignment (=) and equality (==) operators, but here the trap is that candidates may confuse the direction of the comparison or forget that 'a != b' is true when values differ, leading them to incorrectly eliminate correct options like D and E.

Correct answer & explanation
✓
a < b
The expression 'a < b' compares the integer values of a (5) and b (10). Since 5 is less than 10, the relational operator '<' returns the boolean value true.
