Java code to check a number is even or odd using Method
Java code to check a number is even or odd using Method
In this program, we will discuss the Java code to check a number is even or odd using Method
In this program, we are going to learn about how to find odd or even number from given number using the method in the Java language
What is Even or Odd
When the number is divided by 2 and the balance becomes zero and the above number is called as the even number – eg 2,4,6,8,10
and on the other sides when it is divided by 2 and balance becomes 1 they are called odd numbers or uneven numbers
In my previous post, I have explained the various ways to check whether the number is even or odd in Java language
However, in this program, we embed the logic of the check even or odd number program in the method
you can embed the logic of the program to check even or odd numbers using any of the following approaches in the method
Once This program received the number it will check the given number either odd or even.
After receiving the input from the user, it is stored in the variable of num and then program divides the value of num by 2 and displays the output
Program 1
Using modular operator
import java.util.Scanner;
class Even_Odd1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number for check odd or even: ");
int num=scan.nextInt();
//reads the value from the user
find_Oddeven(num);//calling the method
}
//create a user defined metod
static void find_Oddeven(int num){//method definition
if(num%2==0)
System.out.println(num+" is even");
else
System.out.println(num+" is odd");
}
}
When the above code is executed, it produces the following results
Case 1
Enter a number for check odd or even: 234 234 Is even
Case 2
Enter a number for check odd or even: 253 253 is odd
Using modular operator with the return
Program 2
import java.util.Scanner;
class Even_Odd1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
//create a scanner object for input
System.out.print("Enter the number for check odd or even: ");
int num=scan.nextInt();
if(num%2==0)
System.out.println(num+" is even");
else
System.out.println(num+" is odd");
//reads the value from the user
find_Oddeven(num);//calling the method
}
//create a user defined method with return
static boolean find_Oddeven(int num){//method definition
return (num%2==0);//return the value
}
}
When the above code is executed, it produces the following results
Case 1
Enter a number to check odd or even 344 344 is even
Case 2
Enter a number to check odd or even 47 47 is odd
Program 3
Using Bitwise operator
import java.util.Scanner;
class OddEvenMethod5{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number for check odd or even: ");
int num=scan.nextInt();//reads the value from the user
isEvenOrOdd(num); //call the method
}
//create a user define method to find odd or even
static void isEvenOrOdd(int num){//method for find even or odd
if((num & 1) ==1)
System.out.print(num+ "is an odd number");
else
System.out.print(num+ "is an even number");
}
}
When the above code is executed, it produces the following results
Case 1
Enter a number for check odd or even: 654 654 Is an even number
Case 2
Enter a number for check odd or even: 323 323 is an odd number
Program 4
Using ternary operator
import java.util.Scanner;
class OddEvenMethod4{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number for check odd or even: ");
int num=scan.nextInt();//reads the value from the user
isEvenOrOdd(num); //call the method
}
//create a user defined method to fine odd or even
static void isEvenOrOdd(int num){//method for find even or odd
String oddEven=(num % 2 == 0)? "Even":"Odd";
System.out.println(num+" is "+oddEven);
}
}
When the above code is executed, it produces the following results
Case 1
Enter a number for check odd or even: 567 567 Is odd
Case 2
Enter a number for check odd or even: 124 124 is even
Program 5
Using Division operator
import java.util.Scanner;
class OddEvenMethod2{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number for check odd or even: ");
int num=scan.nextInt();//reads the value from the user
isEvenOrOdd(num); //call the method
}
//create a user defined method to find odd even
static void isEvenOrOdd(int num){//method for find even or odd
if((num/2)*2==num)
System.out.println(num+" is even");
else
System.out.println(num+" is odd");
}
}
When the above code is executed, it produces the following results
Case 1
Enter the number for check odd or even: 501 501 is Odd
Case 2
Enter the number for check odd or even: 200 200 is even
Program 6
Using shift operator
import java.util.Scanner;
class OddEvenMethod1{
public static void main (String args[]){
Scanner scan=new Scanner(System.in);
System.out.print("Enter the number for check odd or even: ");
int num=scan.nextInt();//get input from user
isEvenOrOdd(num); //call the method
}
static void isEvenOrOdd(int num){//methods for find even or odd
if(((num >> 1)<<1) ==num)
System.out.print(num+ " is a Even number");
else
System.out.print(num+ " is a Odd number");
}
}
When the above code is executed, it produces the following results
Case 1
Enter the number for check odd or even: 501 501 is a Odd number
Case 2
Enter the number for check odd or even: 200 200 is a Even number
