Thread: variable might not have been initialized...help appreciated

hey guys ive been working on the project and i keep gettin an error here is thy code....

public class Tickets
{
public static void main(String[] args)
 
{
 
 
 DecimalFormat df = new DecimalFormat("#,000.00");
 
 
 
Scanner s = new Scanner(System.in); // create a Scanner object
 String name;
 String input;	// read in user input as a string
 
 
  System.out.println("Welcome To Royals Stadium! Please select your ticket tier then enter quanity!");
System.out.println("(A)Tier 1 $50.00 ");
System.out.println("(B)Tier 2 $40.00 ");
System.out.println("(C)Tier 3 $30.00 ");
System.out.println("Please enter ticket tier A, B, or C: "); 
	char tick1 = (s.nextLine()).charAt(0);
 
System.out.println("Please enter quanity: "); 
int hours1 = Integer.parseInt(s.nextLine());
	int points1;
 
 if(tick1 == 'A' || tick1 == 'a'){
		points1 = 50;
	} // end 'A"
	else if(tick1 =='B' || tick1 == 'b'){
		points1 = 40;
	} // end 'B'
	else if(tick1 =='C' || tick1 == 'c'){
		points1 = 30;
	} // end 'C'
 
 System.out.println("Would you like to add Parking to the Ticket ");	// user prompt
  System.out.println("(Y for Yes, N for No) ");	// user prompt
 input = s.nextLine();
 
 double totalcredits = points1*hours1;   (this is where the error occurs)	
double totalhours = hours1;
	double gpa = (double) totalcredits/totalhours;
	System.out.print("Your Grand ticket total is" + df.format(gpa));

here is the error

Tickets.java:55: variable points1 might not have been initialized
double totalcredits = points1*hours1;
^
1 error
i just cant figure out why its not goin through
thanks for your help!

Lighten up. Yes i can read the error code. I thought I already declared and initialized points1.

int points1; //(declared)
 
if(tick1 == 'A' || tick1 == 'a'){
		points1 = 50;      //( initialed a value)
	} // end 'A"
	else if(tick1 =='B' || tick1 == 'b'){
		points1 = 40;      // ( initialed a value)
	} // end 'B'
	else if(tick1 =='C' || tick1 == 'c'){
		points1 = 30;     // ( initialed a value)
	} // end 'C'

Thanks for your help!

It looks like you have declared and initialized it properly but thats not true. You have declared it correctly but all initialization is happening in conditional loop so there might be a situation where programs flow doesn't pass through any of the loop then no initialization will happen and compiler always try to avoid that situation. This error is pointing to that situation.

Just add this extra line
else
{
points1 = 30;
}

Error will be gone. or you initilize it where you have declared it.
Always remember local member don't get default value as instance variable.

Hope this help. For instance or local variable look here URL
