## What is a logical operation in Java?

A logical operator (sometimes called a “Boolean operator”) in Java programming is an operator that returns a Boolean result that’s based on the Boolean result of one or two other expressions. evaluated before the And operator is applied.

## What is exclusive or in Java?

Bitwise XOR (exclusive or) “^” is an operator in Java that provides the answer ‘1’ if both of the bits in its operands are different, if both of the bits are same then the XOR operator gives the result ‘0’. XOR is a binary operator that is evaluated from left to right.

## What is difference between and || in Java?

Differences between | and || operators in Java | is a bitwise operator and compares each operands bitwise. It is a binary OR Operator and copies a bit to the result it exists in either operands. Whereas || is a logical OR operator and operates on boolean operands.

## What does || mean in C#?

The conditional logical OR operator ||, also known as the “short-circuiting” logical OR operator, computes the logical OR of its operands. The result of x || y is true if either x or y evaluates to true. Otherwise, the result is false. If x evaluates to true, y is not evaluated.

## What are the 3 logical operators?

Common logical operators include AND, OR, and NOT.

## What are the 5 logical operators?

There are five logical operator symbols: tilde, dot, wedge, horseshoe, and triple bar.

## What is XOR example?

Examples: 1 XOR 1 = 0. 1 XOR 0 = 1. 0 XOR 0 = 0. 11102 XOR 10012 = 01112 (this is equivalent to addition without carry)

## What is the difference between logical and Bitwise Operators in Java?

First, logical operators work on boolean expressions and return boolean values (either true or false), whereas bitwise operators work on binary digits of integer values (long, int, short, char, and byte) and return an integer. On the other hand, bitwise operators always evaluate both operands.

## What is the symbol for XOR?

The logic symbols ⊕, Jpq, and ⊻ can be used to denote an XOR operation in algebraic expressions. C-like languages use the caret symbol ^ to denote bitwise XOR. (Note that the caret does not denote logical conjunction (AND) in these languages, despite the similarity of symbol.)

## Can we have this () and super () together?

both this() and super() can not be used together in constructor. this() is used to call default constructor of same class.it should be first statement inside constructor. super() is used to call default constructor of base class.it should be first statement inside constructor.

## What does || mean in Java?

|| is a type of Logical Operator and is read as “OR OR” or “Logical OR“. This operator is used to perform “logical OR” operation, i.e. the function similar to OR gate in digital electronics.

## Which is faster ++ i or i ++?

++i is sometimes faster than, and is never slower than, i++. For intrinsic types like int, it doesn’t matter: ++i and i++ are the same speed. For class types like iterators or the previous FAQ’s Number class, ++i very well might be faster than i++ since the latter might make a copy of the this object.

## Is equal to C#?

The most common way to compare objects in C# is to use the == operator. For predefined value types, the equality operator (==) returns true if the values of its operands are equal, false otherwise. For reference types other than string, == returns true if its two operands refer to the same object.

## Is null in C#?

null (C# Reference) The null keyword is a literal that represents a null reference, one that does not refer to any object. null is the default value of reference-type variables. Ordinary value types cannot be null, except for nullable value types.

## What does || mean in code?

The logical OR operator ( || ) returns the boolean value true if either or both operands is true and returns false otherwise. The second operand is evaluated only if the first operand evaluates to false, because evaluation isn’t needed when the logical OR expression is true.
