## Which operator in Java is right associativity?

Ans. The **= operator** is right associative.

## What is associative in Java?

Associativity **tells the direction of execution of operators that can be either left to right or right to left**. For example, in expression a = b = c = 8 the assignment operator is executed from right to left that means c will be assigned by 8, then b will be assigned by c, and finally a will be assigned by b.

## Is Python right associative?

**Almost all the operators have left-to-right associativity**. For example, multiplication and floor division have the same precedence. Hence, if both of them are present in an expression, the left one is evaluated first. Note: Exponent operator ** has right-to-left associativity in Python.

## Which operator has highest priority?

The operators are listed in order of priority, **group 1** having the highest priority and group 7 the lowest. All operators in the same priority group have the same priority. For example, the exponentiation operator ** has the same priority as the prefix + and prefix – operators and the not operator ¬.

## Which has highest precedence in Java?

In Java, **parentheses() and Array subscript[]** have the highest precedence in Java. For example, Addition and Subtraction have higher precedence than the Left shift and Right shift operators.

## Which is a logical operator?

A logical operator is **a symbol or word used to connect two or more expressions** such that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.

## How are comments written in Java?

**The Java programming language has three kinds of comments:**

- Traditional comments: The first five lines of the listing form one traditional comment. The comment begins with /* and ends with */. …
- End-of-line comments: The text //I? …
- Javadoc comments: A javadoc comment begins with a slash and two asterisks (/**).

## Is Java left associative?

Another difference is that the ++ and – – operators are effectively non-associative in Java.

…

4.14 Order of Operations.

Precedence | Operator | Associativity |
---|---|---|

2 | new | non-associative |

3 | . | left-associative |

4 | ++, – – | non-associative |

5 | – (unary), + (unary), !, ~, ++, – -, (type) | right-associative |

## What is the use of operators?

Comparison Operators are **used to perform comparisons**. Concatenation Operators are used to combine strings. Logical Operators are used to perform logical operations and include AND, OR, or NOT. Boolean Operators include AND, OR, XOR, or NOT and can have one of two values, true or false.

## What is commutativity and associativity?

In math, the associative and commutative properties are **laws applied to addition and multiplication that always exist**. The associative property states that you can re-group numbers and you will get the same answer and the commutative property states that you can move numbers around and still arrive at the same answer.
