What is the difference & and &&?

& is a bitwise operator and compares each operand bitwise. It is a binary AND Operator and copies a bit to the result if it exists in both operands. Whereas && is a logical AND operator and operates on boolean operands.

Whats the difference between and and/or in Java?

For absolute beginners, & is used to represent AND logic operation in Java and | is used to represent OR logic operation. If we use only one & or | then it’s known as “bitwise AND” and bitwise OR operators and if we use double && or || then it’s known as logical or short-circuit AND and OR operators.

Is it better to use && or ||?

because AND has a lower precedence and thus || a higher precedence. These are different in the cases of true, false, false and true, true, false . See https://ideone.com/lsqovs for en elaborate example. Hence, using && and || is safer for they have the highest precedence.

What is differences between logical AND && and bit wise and (&)?

a) The logical and operator ‘&&’ expects its operands to be boolean expressions (either 1 or 0) and returns a boolean value. The bitwise and operator ‘&’ work on Integral (short, int, unsigned, char, bool, unsigned char, long) values and return Integral value.

What is the difference in implementation between & and &&?

& is an operator in programming that performs bit by bit AND operations of the given operands. && is an operator in programming that performs logical AND operation on the multiple decisions. & operator copies a bit to the result if it exists in both operands.

What is the difference between and operator give example?

‘/’ is known as division operater and used for division , for e.g. 10 / 5 = 2 i.e. the quotient whereas ‘\%’ is known as modulus and used for obtaining the remainder of calculation. for e.g. 10 \% 5 = 0 i.e. the remainder.

Is && evaluated before?

The logical-AND operator ( && ) has higher precedence than the logical-OR operator ( || ), so q && r is grouped as an operand. Since the logical operators guarantee evaluation of operands from left to right, q && r is evaluated before s– .

How is && evaluated in JavaScript?

Logical AND ( && ) evaluates operands from left to right, returning immediately with the value of the first falsy operand it encounters; if all values are truthy, the value of the last operand is returned. If a value can be converted to true , the value is so-called truthy.

What is the difference between & and && operator explain with suitable example?

The && operator is purely a Logical operator. The basic difference between the & and && operator is that the & operator evaluate both sides of the expression whereas, the && operator evaluates only the left-hand side of the expression to obtain the final result.
