Thread: why is the program not entering the if statement?

package catalog;

import java.util.*;

public class Catalog {

static String products[] = new String[3];
static int answer;

public static void main(String[] args) {

System.out.println("------------------");
System.out.println("Shopping Catalog");
System.out.println("------------------");

String[] pCode = new String[3];
float pPrice[] = new float[3];
int orderNum = 0;
int quantity=0;

Scanner s = new Scanner(System.in);
System.out.println("------------------------------------------");
System.out.println("condensed milk [M3487], $9.50 per can.");
System.out.println("");
System.out.println("Distilled Water [W3876], $3.00 a bottle.");
System.out.println("");
System.out.println("Pack Rice [R9983], $12.75 for 5lbs.");
System.out.println("------------------------------------------");




do{

System.out.println("Please enter order number (0 to stop)");
pCode[orderNum] = s.nextLine();

if(pCode[orderNum] == "M3487"){
System.out.println("condensed milk $9.50");
System.out.println("Enter Quantity");
quantity = s.nextInt();
}//close if statement
orderNum++;
if(answer == 0){
break;
}//close if
}while(true);//close while loop

}//close main method

}//close class

Please format your code for better readability.

if(pCode[orderNum] == "M3487")

use equals() method instead of == operator for comparing strings like this..

if (pCode[orderNum].equals("M3487"))

thank you
