Which operator is used to calculate the remainder in Java?

In Java, the operator used to calculate the remainder of a division operation is the modulus operator, represented by the percent symbol (%). When you use this operator between two numbers, it provides the remainder left over after dividing the first number by the second. For example, in the expression 7 % 3, the result is 1 because when you divide 7 by 3, the quotient is 2 and the remainder is 1.

This operator is essential when performing operations that require determining how much is left over after division, which is particularly useful in scenarios like determining if a number is even or odd, or when evaluating conditions that involve periodicity or cycles. The use of the modulus operator enables programmers to easily manage these requirements within their code.
