This is the code to modify i have a few ideas on how to do it but would like a walk through. import java. util. scanner; public class drawhalfarrow {public static void main(string[] args) {scanner scnr = new scanner(system. in); int arrowbaseheight = 0; int arrowbasewidth = 0; int arrowheadwidth = 0; system. out. println("enter arrow base height: "); arrowbaseheight = scnr. nextint(); system. out. println("enter arrow base width: "); arrowbasewidth = scnr. nextint(); system. out. println("enter arrow head width: "); arrowheadwidth = scnr. nextint(); string ast = ""; for (int x = 1; x < = arrowbasewidth; x++) {ast += "*"; }for (i = 1; i < = arrowbaseheight; ++i) {system. out. println(ast); }int tempheadwidth = arrowheadwidth; for (int y = 1; y < = arrowheadwidth; y++) {for(int z = tempheadwidth; z > 0; {system. out. print("*"); } tempheadwidth -= 1; system. out. println();
