Answer:
here is code in java.
import java.util.*;
class Main
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// Scanner class object to read the input integer
Scanner scr=new Scanner(System.in);
// ask user to enter the input
System.out.print("enter a number:");
// read the input
int x=scr.nextInt();
// call the function with parameter "x"
activity(x);
}catch(Exception ex){
return;}
}
// activity function to perform given tasks
public static void activity(int x)
{
// print all the Numbers from 1 to x
System.out.print("Numbers:");
for(int i=1;i<=x;i++)
{
System.out.print(i+" ");
}
System.out.println();
// print all the Evens from 1 to x
System.out.print("Evens:");
for(int i=1;i<=x;i++)
{
if(i%2==0)
System.out.print(i+" ");
}
System.out.println();
// replace divisible of 5 and 7 with "fiver" and "ssss"
System.out.print("Activity:");
for(int i=1;i<=x;i++)
{
if(i%5==0)
System.out.print("fiver ");
else if(i%7==0)
System.out.print("ssss ");
else
System.out.print(i+" ");
}
}
}
Explanation:
Read an integer with the help of Scanner class object and assign it to variable "x". Call the function activity() with parameter "x". In the activity function, first print "Numbers" followed by all numbers from 1 to X. Then print header "Evens" followed by all the even number from 1 to x. In last print "Activity" header followed by numbers from 1 to x and replace a number with "fiver" if it is divisible by 5 or replace with "ssss" if it divisible by 7.
Output:
enter a number:17
Numbers:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
Evens:2 4 6 8 10 12 14 16
Activity:1 2 3 4 fiver 6 ssss 8 9 fiver 11 12 13 ssss fiver 16 17
