х CO1109 ZB 2019-2020 Q... UL20/0576 Page 10 of 22 (c) Consider the Bow Tie class, below import java.util.Scanner; class Bowtie public static void main(Stringil args) Scanner in - new Scanner(System.in); System.out.print("Enter Size"); int size-in.nextInt(): int x = 1 int midpoint - size/ 21 if (isize 2) -- 0) midPoint- for (int i=0; i<sizes i++) for(int -0; j<size: j++){ 18 (//missing boolean condition System.out.print(""); else System.out.print(""); > 1 (midpoint) *** 1/ height of shapes whose size is an odd number - size it (i midpoint) // height of shapes whose size is an even number - size-1 System.out.println() The class will ask the user for a number, and will print out a shape whose size varies, depending on the number entered, for example size size- The boolean condition is missing from their statement in the inner for loop. Give the missing boolean condition 18 mars UL20/0576 Page 11 of 22

Answer 1

MISSING IF CONDITION:

if(x>j || j>midPoint-x+size/2)

//JAVA CODE TO COPY//
import java.util.Scanner;
class BowTie
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print("\nEnter Size>");
int size = in.nextInt();
int x=1;
int midPoint=size/2;
if((size%2)==0)
midPoint--;
for(int i=0; i<size; i++){
for(int j=0; j<size; j++)
{
if(x>j || j>midPoint-x+size/2)
System.out.print("*");
else
System.out.print(" ");
}
if(i<midPoint)
x++;
//height of shapes whose size is an odd
//number = size
if(i>=midPoint)
x--;
//height of shapes whose size is an
//even number = size-1;
System.out.println();
}
}
}
