Chapter 2: Operators Flashcards
A Java operator is a special symbol applied to operands to return a result.
If false, why?
True
Java supports unary, binary, and ternary operators.
If false, why?
True
Operator precedence determines the evaluation order of operators.
True
The multiplication operator (*) has a higher precedence than addition (+).
If false, why?
True
Parentheses can override Java’s default operator precedence.
If false, why?
True.
Java guarantees right-to-left evaluation for operators with the same precedence.
If false, why?
False – Java guarantees left-to-right evaluation for operators of the same precedence.
Pre-unary operators (++x, –x) are evaluated right-to-left.
If false, why?
False – Pre-unary operators are evaluated left-to-right.
The bitwise complement () is evaluated left-to-right.
If false, why?
False – The bitwise complement operator () is evaluated right-to-left.
The shift operators («,»_space;,»_space;>) are evaluated right-to-left.
If false, why?
False – Shift operators are evaluated left-to-right.
The arrow operator (->) is a unary operator.
If false, why?
False – The arrow operator (->) is a binary operator representing a relationship between two operands.
Logical AND (&) is evaluated right-to-left.
If false, why?
False – Logical AND (&) is evaluated left-to-right
The ternary operator (? :) is evaluated left-to-right.
If false, why?
False – Left-to-right evaluation of condition, but right-to-left associativity for nested ternary operators.
The logical complement operator (!) cannot be applied to numeric expressions.
✅ True
The post-increment operator y++ increases the value by 1 but returns the original value.
✅ True
The negation operator (-) can be applied to boolean expressions.
❌ False (It can only be applied to numeric expressions.)
The logical complement operator (!) can be applied to integer values.
❌ False (It can only be applied to boolean expressions.)
The ~ operator inverts only 0 bits and leaves 1 bits unchanged.
❌ False (It inverts all bits, flipping both 0s and 1s.)
The pre-increment operator ++w returns the original value before incrementing.
❌ False (It returns the new value after incrementing.)
The bitwise complement operator (~) can be applied to boolean values.
❌ False (It can only be applied to integer numeric types.)
Increment and decrement operators have a lower precedence than binary arithmetic operators.
❌ False (They have a higher precedence.)
The post-decrement operator z– returns the new value after decrementing.
❌ False (It returns the original value before decrementing.)
The logical complement operator (!) is considered a binary operator.
❌ False (It is a unary operator, not binary.)
The negation operator (-) changes the absolute value of a numeric expression but keeps its sign unchanged.
❌ False (It reverses the sign, making positive values negative and vice versa.)
The ‘+’’+’ and ‘-‘’-‘ operators can be applied to boolean values.
❌ False (They can only be applied to numeric types.)
