Question

This is a java code but I need to understand the logic of how is going to run. Can someone help please.

    int i = 1;
   while (i <= 5) {
       xMethod(i);
        i++;

    }

    System.out.println("i is " + i);
}

public static void xMethod(int i) {
    do {
        if (i % 2 != 0)
            System.out.print(i + " ");
        i--;
    }
    while (i >= 1);
    System.out.println();

ANSWER: Here i am giving you the code and output and explanation is given in the commented part of the code .

CODE:

public class Demo {
  
  

   public static void xMethod(int i) {
   do {
   if (i % 2 != 0) // Here in this method it is a do while loop and in this if this condition we are checking i is divisible of 2 or not if not then printing the value of i
   System.out.print(i + " ");
   i--;
   }while (i >= 1); // and this do while will run untill the value of the i will become to 1
   System.out.println();
   }
public static void main (String[] args)
{
   int i = 1;
    while (i <= 5) { // Here it is sending the value of i=1 initially after that it is paasing the value of i=1 in xMethod(i) and the method explanation is given above here in this while loop valus of will 1=1,2,3,4,5 and sent to the that method xMethod().
    xMethod(i);
    i++;

    }

    System.out.println("i is " + i); // here we are printing the value of i which will be 6 after ending the while you have to notice here value of of in the end will become 6 and condition becomes false in this above while loop.
    }
  
  
     
   }

OUTPUT:
