This java program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. (1) Complete the data read in part of the program. Then modify the given program to use a loop to output an arrow base of height arrowBaseHeight. (2) Modify the given program to use a loop to output an arrow base of width arrowBaseWidth. Use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow base. (3) Modify the given program to use a loop to output an arrowhead of width arrowHeadWidth. Use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrowhead. (4) Modify the given program to only accept an arrowhead width that is larger than the arrow base width. Use a validation loop to continue prompting the user for an arrowhead width until the value is larger than the arrow base width. while (Your condition here) { // Prompt user for a valid arrowhead value } Example output for arrowBaseHeight = 5, arrowBaseWidth = 2, and arrowHeadWidth = 4: Enter arrow base height: 5 Enter arrow base width: 2 Enter arrow head width: 4 ** ** ** ** ** **** *** ** * Code: import java.util.Scanner; public class DrawHalfArrow { public static void main(String[] args) { int arrowBaseHeight; int arrowBaseWidth; int arrowHeadWidth; //Code here to read in the arrowBaseHeight //Code here to read in the arrowBaseWeight //Code here to read in the arrowBaseWidth System.out.println(""); // Draw arrow base (height = 3, width = 2) System.out.println("**"); System.out.println("**"); System.out.println("**"); // Draw arrow head (width = 4) System.out.println("****"); System.out.println("***"); System.out.println("**"); System.out.println("*"); } }

(1) Complete the data read in part of the program. Then modify the given program to use a loop to output an arrow base of height arrowBaseHeight.
(2) Modify the given program to use a loop to output an arrow base of width arrowBaseWidth. Use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrow base.
(3) Modify the given program to use a loop to output an arrowhead of width arrowHeadWidth. Use a nested loop in which the inner loop draws the *’s, and the outer loop iterates a number of times equal to the height of the arrowhead.
(4) Modify the given program to only accept an arrowhead width that is larger than the arrow base width. Use a validation loop to continue prompting the user for an arrowhead width until the value is larger than the arrow base width.
while (Your condition here) {
// Prompt user for a valid arrowhead value }
Example output for arrowBaseHeight = 5, arrowBaseWidth = 2, and arrowHeadWidth = 4:
Enter arrow base height:
5
Enter arrow base width:
2
Enter arrow head width:
4
