In this article, we will show you, How to write a Program to Count Even and Odd Numbers in an Array using For Loop, While Loop, and Functions with example. Then, the result is printed on the screen using string concatenation. Javatpoint Services JavaTpoint offers too many high quality services. If it is True, we are returning Value 1 otherwise, 0. These are some logic which you may use to determine if a number is odd or even. In this article we will write Java Odd Even Program to show you, How to check whether the given number is Odd or Even number using If Statement and Conditional Operator with example In we have an % Module Arithmetic Operator to check the remainder.
Java Program to Count Even and Odd Numbers in an Array using For Loop This allows the user to enter the size, and the One Dimensional elements. Now, to check whether num is even or odd, we calculate its remainder using % operator and check if it is divisible by 2 or not. Within the function, we used If statement to check whether the given number is perfectly divisible by 2 or not. Java Program to Count Even and Odd Numbers in an Array using While Loop This is same as above but this time we used to count the even and odd numbers an array. Odd numbers are those which are not divisible by 2. Else, we print num is odd. Next define an object name 'sc' of Scanner class.
So we can use it to find whether the number is odd or even. If num is divisible by 2, we print num is even. On entering the number 285965, following output appears. Example 2: Check whether a number is even or odd using ternary operator import java. All Java program needs one main function from where it starts executing program.
But this time we created separate method to , and another method to. Consider an integer 'n' we can first divide it by two and then multiply it by two if the result is same as the original number then the number is even otherwise it is odd. For this, we use if. . If it is True, we are printing Even Number statement otherwise, Odd Number statement using System.
But the interviewer may trick you to write Java program to check even or odd number without using modulus and division operator. Then define a class name 'pn'. Numbers like 2,4,6,8,10, etc are even. If the condition is True statement inside the If block will be executed otherwise, it will execute the statement inside the else block Thank You for Visiting Our Blog. As you have studied in Mathematics that in decimal number system even numbers are divisible by two while odd numbers are not so we can use modulus operator % which returns remainder, for example, 4%3 gives 1 remainder when four is divided by three. Program to check even or odd number using modulus operator It is easy to check if a number is even or odd using modulus operator. We can also check if num is even or odd by using ternary operator in Java.
Hope the logic discussed in this post is useful. The size of array will be of type integer and will get stored in variable a using the object 'sc' of Scanner class. The for loop will start from 0 and goes one less, up to the value assigned to 'a'. Java Program to Find Odd or Even import java. Here I have solved it using repeated subtraction.
For a definition of even and odd number check the below links. Even Odd Program Even numbers are those which are divisible by 2. As you can see it is returning Odd Number as Output You can observe from the above code that, we used if condition to check whether the remainder of the given integer divisible by 2 is 0 or not and print as per the result. C program to check odd or even: We will determine whether a number is odd or even by using different methods all are provided with a C language program. The entered number is then stored in a variable num. Java Program to Find Odd or Even number In below code i will show you how to design Java Program to Find Odd or Even number. Note, this is the first method that we created with void keyword and this method will check for even or odd and print the output from the EvenOrOdd Class itself.
So, we used the If condition to check whether the remainder of the number divided by 2 is exactly equal to 0 or not. So when the interviewer asks to write a Java program to check even or odd number without using modulus and division operator then you can use this logic. Let us enter 28 to check the other output Java Odd Even Program using Methods In this we are using the same steps that we followed in our first example but we separated the logic and placed in the separate method. Even numbers are those which are divisible by 2, and which numbers are not divisible 2 is called odd numbers. Now, implement for loop to insert values into the array. If you want to return any value then replace void with data type and add return keyword.
