java - class X extends Y. Symbols won't transfer -
i've searched through quite few questions relating this, i'm not sure problem is. when run lab4b_info, variables m1 , m2 being identified location; however, information m1 , m2 come sister program lab4a_receipt. result, i'm receiving error program cannot find symbol.
to put bit more simply, need coins , dollars information @ bottom of 4a, extend 4b. here 2 programs in question.
import javax.swing.*; import javax.swing.joptionpane; class lab4a_receipt { public static void receipt() { string c1, c2, c3, p, s, d, pay; double r1, r2, r3, pc = 0, sc = 0, dc = 0, ment, total; c1 = joptionpane.showinputdialog("would pizza? yes (1) or no(2)?"); r1 = integer.parseint(c1); if (r1 != 1) { pc = 0; } else if (r1 == 1) { p = joptionpane.showinputdialog("excellent! kind? pepperoni (1) $10? cheese (2) $8? (3) $12!?"); pc = integer.parseint(p); } if (pc == 1) { pc = 10; } else if (pc == 2) { pc = 8; } else if (pc == 3) { pc = 12; } /// c2 = joptionpane.showinputdialog("would sandwhich? yes (1) or no(2)?"); r2 = integer.parseint(c2); if (r2 != 1) { sc = 0; } else if (r2 == 1) { s = joptionpane.showinputdialog("okee doke. stromboli (1) $7, or ham , cheese (2) $6?"); sc = integer.parseint(s); } if (sc == 1) { sc = 7; } else if (sc == 2) { sc = 6; } /// c3 = joptionpane.showinputdialog("how drink? yes (1) or no(2)?"); r3 = integer.parseint(c3); if (r3 != 1) { dc = 0; } else if (r3 == 1) { d = joptionpane.showinputdialog("okay then. coke (1), pepsi (2), or doctor peper (3)? $1."); dc = integer.parseint(d); } if (dc == 1) { dc = 1; } else if (dc == 2) { dc = 1; } else if (dc == 3) { dc = 1; } /// total = pc + sc + dc; double tax = (total * 1.06); double round = math.round(tax * 100.0) / 100.0; system.out.println("pizza: $" + pc + " sandwhich: $" + sc + " drink: $" + dc + " total: $" + round + ""); string output = "order\tcost"; output += "\n" + "pizza" + "\t" + pc; output += "\n" + "sandwhich" + "\t" + sc; output += "\n" + "drink" + "\t" + dc; output += "\n" + "total" + "\t" + total; jtextarea outputarea = new jtextarea(); outputarea.settext(output); joptionpane.showmessagedialog(null, outputarea, "receipt", joptionpane.information_message); pay = joptionpane.showinputdialog("what pay with?"); ment = integer.parseint(pay); system.out.println("you've decided pay $" + ment + ""); //////////////////dollars double dol = math.floor(ment - round); int m1 = (int) dol; /////////////////////coin double cha = math.round((ment - round) * 100.0) / 100.0; double = math.floor(((dol - cha) * 100) * -1); int m2 = (int) a; } } and here's second part.
class lab4b_info extends lab4a_receipt { public static void main(string[] args) { int x = m1; int y = m2; system.out.println("change:"); int d1 = x / 50; if (d1 > 0) { x = x % 50; system.out.println(d1 + " 50 dollar bill(s)"); } int d2 = x / 20; if (d2 > 0) { x = x % 20; system.out.println(d2 + " 20 dollar bill(s)"); } int d3 = x / 10; if (d3 > 0) { x = x % 10; system.out.println(d3 + " 10 dollar bill(s)"); } int d4 = x / 5; if (d4 > 0) { x = x % 5; system.out.println(d4 + " 5 dollar bill(s)"); } int d5 = x; if (d5 > 0) { system.out.println(d5 + " 1 dollar bill(s)"); } int q = y / 25; if (q > 0) { y = y % 25; system.out.println(q + " quarter(s)"); } int d = y / 10; if (d > 0) { y = y % 10; system.out.println(d + " dime(s)"); } int n = y / 5; if (n > 0) { y = y % 5; system.out.println(n + " nickle(s)"); } int p = y; if (p > 0) { system.out.println(p + " penny(s)"); } } } it's may small detail i've overlooked, programming sound. when put together, runs fine.
