Java program to find if a number is even or odd?<\/h2>\n

Even or Odd: If the number is divisible by 2 then it is even, otherwise it is an odd number. On this page, we will write a Java program that checks if a number is odd or even.<\/p>\n

Mathematical Definition<\/strong><\/h2>\n

The formal mathematical definition of an even number is that it is an integer of the form n = 2i, where i is an integer. An odd number is an integer of the form n = 2i + 1.<\/p>\n

even\u00a0 =\u00a0\u00a0 { 2i\u00a0 such that where i belongs to Z
\nodd\u00a0\u00a0\u00a0 =\u00a0\u00a0 { 2i + 1 such that where i belongs to Z<\/p>\n

We have used the modulus operator to find the remainder in the java program. It is an important arithmetical operator also known as a remainder operator. It returns the remainder of the two numbers. For instance 5 % 2 is 1 because 5 divided by 2 leaves a remainder of 1. In this program, we check for n % 2\u00a0 is 0 i.e nothing left after dividing the number by 2. So the number is an even number.<\/p>\n
