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);
    }
    }
} 

help me please

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;
