Code:: public static void main(String[] args) throws IOException{ int nofaktur ; int kodebrang ; double jmltransaksi; double hargabarang; double totalharga; double diskon ; double totalbayar; DataInputStream input = new DataInputStream(System.in); System.out.print("input nofaktur ="); nofaktur=Integer.parseInt(input.readLine()); System.out.print("input kodebarang ="); kodebrang=Integer.parseInt(input.readLine()); System.out.print("jmltransaksi = "); jmltransaksi=Integer.parseInt(input.readLine()); if (kodebrang == 1) { hargabarang = 500000; } else if (kodebrang==2) { hargabarang = 100000; } else {hargabarang = 50000; } totalharga = hargabarang * jmltransaksi;{ if ((kodebrang == 1)&&(jmltransaksi >= 10)) { diskon = (int) (5 / 100 * totalharga);} else if (((kodebrang== 1)||(kodebrang== 2)&&(jmltransaksi >= 5))) { diskon = (int) (7 / 100 * totalharga);} totalbayar=totalharga-diskon ; System.out.print("hargabarang =");System.out.print(hargabarang); System.out.print("totalharga =");System.out.print(totalharga); System.out.print("diskon =");System.out.print(diskon); System.out.print("totalbayar =");System.out.print(totalbayar); } } }

you have to give initial values for within function defined variables which are :

Code:: int nofaktur =0; int kodebrang=0 ; double jmltransaksi=0.0d; double hargabarang=0.0d; double totalharga=0.0d; double diskon=0.0d ; double totalbayar=0.0d;
