## What are unary and binary operator?

There are two types of mathematical operators: unary and binary. Unary operators perform an action with a single operand. Binary operators perform actions with two operands. In a complex expression, (two or more operands) the order of evaluation depends on precedence rules.

## What is binary operator in Java?

The BinaryOperator Interface<T> is a part of the java. util. function package which has been introduced since Java 8, to implement functional programming in Java. It represents a binary operator which takes two operands and operates on them to produce a result.

## What is binary operator with example?

Binary operators are those operators that work with two operands. For example, a common binary expression would be a + b—the addition operator (+) surrounded by two operands. The binary operators are further subdivided into arithmetic, relational, logical, and assignment operators.

## Is unary or binary operator?

Solution

Unary Operators Binary Operators
(i) The operators which act upon a single operand are called unary operators. (i) The operators which require two operands for their action are called binary operators.

## What is the difference between binary and ternary operator?

## What is the Behaviour of binary operator?

Binary operators are operators that affect operands, which are the values on either side of the operator. For example, take a + b. In this expression, a and b are operands, and + is the operator. All Binary operators are infix, meaning they are in between two operands.

## Which is called ternary operator?

The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark ( ? ), then an expression to execute if the condition is truthy followed by a colon ( : ), and finally the expression to execute if the condition is falsy.

## What does 3 dots mean in Java?

The “Three Dots” in java is called the Variable Arguments or varargs. It allows the method to accept zero or multiple arguments. Varargs are very helpful if you don’t know how many arguments you will have to pass in the method.

## What does \ s+ mean in Java?
