Question

Java public class Odds { public static void main(String[] args) { printOdds(3); printOdds(17/2); int x = 25; printOdds(37 – x +1); } public static void printOdds(int n) { for (int i = 1; i <= n; i++) { int odd = 2*i -1; System.out.print(odd + " "); } System.out.println(); } }

Write the output.

Answer 1

The output of the given program is :

1 3 5

1 3 5 7 9 11 13 15

1 3 5 7 9 11 13 15 17 19 21 23 25

Explanation:

The description of the following program can be given as:

• In the given java program firstly we define a class that is "Odds". In this class, we define the main method. In this method, we call printOdds() function three times.
• In the first time calling, we pass 3 in the function parameter. So the function print 3 odd number that is 1 3 5.
• In the second time calling, we pass value 17/2 in function parameter which is 8. So, the function print 8 odd number that is 1 3 5 7.....15
• In third time calling we define an integer variable that is x in this variable we assign value that is 25 and call function that calculates value (37-x+1) that is 13. So, the function print 13 odd numbers that is 1 3 5 7..........25.
• In the last, we define the printOdds() function that is outside the class that prints odd numbers.
