What are the operators in Scala?

What are the operators in Scala?

3.2. There are five relational operators in Scala: Greater than (>) Less than (<) Greater than or equal to (>=)

What are the 3 operators?

The three main types of operators are Arithmetical, Logical and Relational.

What is lambda function in Scala?

Scala lambda functions are anonymous functions. They reduce the line of code and make the function more readable and convenient to define. We can also reuse them. We can use this lambda function to iterate our collection data structure and performed any kind of operation on them.

What is this operator called?

Logical (or Relational) Operators:

Operator Description Example
&& Called Logical AND operator. If both the operands are non zero then then condition becomes true. (A && B) is true.
|| Called Logical OR Operator. If any of the two operands is non zero then then condition becomes true. (A || B) is true.

What is currying in Scala?

Currying is the process of converting a function with multiple arguments into a sequence of functions that take one argument. Each function returns another function that consumes the following argument.

What is trait in Scala?

A Trait is a concept pre-dominantly used in object-oriented programming, which can extend the functionality of a class using a set of methods. Traits are similar in spirit to interfaces in Java programming language. Unlike a class, Scala traits cannot be instantiated and have no arguments or parameters.

What are operators in programming?

An operator, in computer programing, is a symbol that usually represents an action or process. These symbols were adapted from mathematics and logic. An operator is capable of manipulating a certain value or operand.

What is the += operator called?

The addition assignment operator ( += ) adds the value of the right operand to a variable and assigns the result to the variable.

What is Monad in Scala?

In Scala, Monads is a construction which performs successive calculations. It is an object which covers the other object. It is worth noting that here, the output of an operation at some step is an input to another computations, which is a parent to the recent step of the program stated.

What are the different types of operators in Scala?

There are different types of operators used in Scala as follows: These are used to perform arithmetic/mathematical operations on operands. Addition (+) operator adds two operands. For example, x+y. Subtraction (-) operator subtracts two operands. For example, x-y. Multiplication (*) operator multiplies two operands. For example, x*y.

What is operator precedence in Scala?

Operators Precedence in Scala Operator precedence determines the grouping of terms in an expression. This affects how an expression is evaluated. Certain operators have higher precedence than others; for example, the multiplication operator has higher precedence than the addition operator −

What are the bitwise operators supported by Scala?

Bitwise operator works on bits and perform bit by bit operation. The truth tables for &, |, and ^ are as follows − Assume if A = 60; and B = 13; now in binary format they will be as follows − The Bitwise operators supported by Scala language is listed in the following table. Assume variable A holds 60 and variable B holds 13, then −

What is infix operator in Scala?

In Scala, operators are methods. Any method with a single parameter can be used as an infix operator. For example, + can be called with dot-notation: However, it’s easier to read as an infix operator: You can use any legal identifier as an operator.
