An integer (never a fraction) that cannot be divided exactly by 2. For example, 3 is an odd number, i.e., 3 % 2 = 1 (not zero).
Note: % is a Modulus (Division Remainder) operator, it finds the remainder after division of one number by another. Please check our Arithmetic Operators for more details.
In the following example, we will find all the Odd Numbers between 10 and 25 using for loop.
Example
Java Compiler
public class myClass
{
public static void main(String[] args)
{
int start =10;
int end =25;
System.out.format("Odd numbers between %d and %d:\n", start, end);
for(start=start; start<=end; start++)
{
if(start %2!=0)
System.out.print(start +" ");
}
}
}
Output
Odd numbers between 10 and 25:
11 13 15 17 19 21 23 25
Using While Loop
In the following example, we will find all the Odd Numbers between 10 and 25 using while loop.
Example
Java Compiler
public class myClass
{
public static void main(String[] args)
{
int start =10;
int end =25;
System.out.format("Odd numbers between %d and %d:\n", start, end);
while(start <= end)
{
if(start %2!=0)
System.out.print(start +" ");
start++;
}
}
}
Output
Odd numbers between 10 and 25:
11 13 15 17 19 21 23 25
Using do while Loop
In the following example, we will find all the Odd Numbers between 10 and 25 using do while loop.
Example
Java Compiler
public class myClass
{
public static void main(String[] args)
{
int start =10;
int end =25;
System.out.format("Odd numbers between %d and %d:\n", start, end);
do {
if(start %2!=0)
System.out.print(start +" ");
start++;
}while(start <= end);
}
}
Output
Odd numbers between 10 and 25:
11 13 15 17 19 21 23 25
Odd Numbers between any Given Range
In the following example, we will find all the Odd numbers between any given range.
Example
Java Compiler
import java.util.Scanner;
public class myClass
{
public static void main(String[] args)
{
Scanner reader =new Scanner(System.in);
System.out.print("Enter a (int) starting number: ");
int start = reader.nextInt();
System.out.print("Enter an (int) ending number: ");
int end = reader.nextInt();
System.out.format("\nOdd numbers between %d and %d:\n", start, end);
for(start=start; start<=end; start++)
{
if(start %2!=0)
System.out.print(start +" ");
}
}
}
Output
Enter a (int) starting number: 5
Enter an (int) ending number: 15
Odd numbers between 5 and 15:
5 7 9 11 13 15
Check Whether the Given Number is Odd or Even
In the following example, we will check whether the given number is an Odd number or Even number.
Example
Java Compiler
import java.util.Scanner;
public class myClass
{
public static void main(String[] args)
{
Scanner reader =new Scanner(System.in);
System.out.print("Enter a (int) number: ");
int num = reader.nextInt();
if(num %2==0)
System.out.format("%d is an even number", num);
elseSystem.out.format("%d is an odd number", num);
}
}
Output
Enter a (int) number: 5
5 is an odd number
