Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
==: Compares two values for equality
The correct matches are: == for equality, && for logical AND. Common confusions include mixing assignment (=) with comparison (==) and misunderstanding the ternary operator vs. logical operators.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
==: Compares two values for equality
Why this is correct
The == operator is used for equality comparison between two values.
&&: Returns true if both operands are true
Why this is correct
The && operator is the logical AND operator, which returns true only if both operands are true.
!=: Used to assign a value to a variable
Why it's wrong here
Incorrect. The != operator is used for inequality comparison, not assignment. Assignment is done with =.
instanceof: Used to compare two primitive values
Why it's wrong here
Incorrect. instanceof checks if an object is an instance of a specific class, not for comparing primitive values.
?:: Used to perform a logical OR operation
Why it's wrong here
Incorrect. The ternary operator ?: is used for conditional expression, not logical OR. Logical OR is ||.
