java - Make a program that will ask for product code, the quantity of the product, and sums up all the prices -

i've been having hard time doing , i've been searching ideas on how code down i'm still beginner. here's source code. maybe you'll idea reading it. it's not running should though.

import javax.swing.joptionpane; public class sto {     public static void main(string args[])     {         char s;                 {             int pcod=0, qua;             int[] cod={101, 102, 103, 104, 105, 106, 107, 108, 109, 110};             double[] pri={1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9, 0.1};             double [] sal=new double[10];             string[] pro={"q", "w", "e", "r", "t", "y", "u", "i", "o", "p"};                         {                 if(pcod>=101||pcod<=110)                 {                     pcod=integer.parseint(joptionpane.showinputdialog(null,"enter product code:"));                     for(int i=0;i<10;i++)                     {                         if(pcod==cod[i])                         {                             qua=integer.parseint(joptionpane.showinputdialog(null,"enter quantity:"));                             sal[i]=pri[i]*qua;                             joptionpane.showmessagedialog(null,"you bought:\n"+pro[i]+"......"+pri[i]+" pesos x"+qua);                         }                     }                 }                 else                 if(pcod<=101||pcod>=110)                     joptionpane.showmessagedialog(null,"invalid product code");                     //some codes here make return enter product code again.             }while(pcod!=00);             for(int d=0;d<10;d++)                 sal[d]=qua;             joptionpane.showmessagedialog(null,"total sales.........."+sal[d]+" pesos");             s=joptionpane.showinputdialog(null,"shop again?(y/n)").charat(0);         }         while(s=='y');     } } 

// .. problem in next few lines for(int d=0;d<10;d++)     sal[d]=qua; joptionpane.showmessagedialog(null,"total sales.........."+sal[d]+" pesos"); 

lacking brackets, for loop includes next, indented code line. attribute d defined inside for loop statement, , goes out of focus beyond loop (cannot referenced/used in option pane).

to fix it, put { , } around 2 lines (one set of brackets include both lines).

that leads next problem.

int pcod=0, qua; 

at point, pcod 0 qua has no value. compiler warn, might not have been initialized. quick fix give default value, might not fit logic of app., if exception thrown while parsing input int value.
