Question

This is a JAVA question. How do I preserve my initial price so that subsequent calculations in the IF statement always use the initial price? I'd prefer not to make a separate variable if possible. Here is the part of the code that the question refers to.

   System.out.println("Please enter the cinema ticket price: ");
       price = scan.nextDouble();
       System.out.println("Please enter age (0 to quit): ");
       age = scan.nextInt();
      
      
       //Sentinel Value
       while (age != 0)
       {
      
       //Ticket Price
           if (age < 5)
           {
               price = 0;
               System.out.println("Your age: " + age);
               System.out.println("Your ticket price is " + cFmt.format(price) + " which is free.");
           }
           else if (age <= 12)
           {
               price /= 2;
               System.out.println("Your age: " + age);
               System.out.println("Your ticket price is " + cFmt.format(price) + " which is half price.");
           }
           else if (age <= 54)
           {
               System.out.println("Your age: " + age);
               System.out.println("Your ticket price is " + cFmt.format(price) + " which is full price.");
           }
           else if (age >= 55)
           {
               price = 0;
               System.out.println("Your age: " + age);
               System.out.println("Your ticket price is " + cFmt.format(price) + " which is free.");
           }
          
           System.out.println(" Please enter age (0 to quit): ");
           age = scan.nextInt();
          
       }

Explanation / Answer

Scanner scan=new Scanner(System.in);
   System.out.println("Please enter the cinema ticket price: ");
double price = scan.nextDouble();
System.out.println("Please enter age (0 to quit): ");
int age = scan.nextInt();
double temp=age;


while (age != 0)
{

//Ticket Price
if (age < 5)
{

System.out.println("Your age: " + age);
System.out.println("Your ticket price is " + cFmt.format(0) + " which is free.");
}
else if (age <= 12)
{
  
System.out.println("Your age: " + age);
System.out.println("Your ticket price is " + cFmt.format(price/2) + " which is half price.");
}
else if (age <= 54)
{
System.out.println("Your age: " + age);
System.out.println("Your ticket price is " + cFmt.format(price) + " which is full price.");
}
else if (age >= 55)
{
  
System.out.println("Your age: " + age);
System.out.println("Your ticket price is " + cFmt.format(0) + " which is free.");
}

System.out.println(" Please enter age (0 to quit): ");
age = scan.nextInt();

with out making it equal to price just send the half value of price
