While Loops
I have this program, and I when I press 1 I want the program to quit, and 2 to continue, I can't seem to get this to work. It complies fine, and it will run, but I can't get the press 1 to exit and press 2 to continue to work. For some reason I need to put option=0 because it says variable not initialized if I don't
class Questions
{
// --Main Method--
publicstaticvoid main(String[]args)
{
// --Title--
System.out.println("Ask any question, and get an answer!");//introduces the program
System.out.println("Ask your question:");
question();
loop();
}
staticvoid question()
{
// --Variable Declaration and Initialization--
String question;
// --Requests Input--
question = KeyIn.aString();//asks the user to input a question
int k = EasyRandom.getInt(10);//randomly picks an answer
answer(k);//outputs the answer
// --Output--
next();
}
staticvoid next()
{
int option = 0;
System.out.println("Press 1 to exit, 2 to continue.");//gives to option to continue or to quit the program
option = KeyIn.anInt();//user inputs what they want to do
}
staticvoid loop()
{
int option = 0;
while (option == 2)
{
question();//if the number is 2 then it will continue with another question
}
break;
System.out.println("End program");//if number =1 will exit program
}
staticvoid answer(int k)
{
switch(k)
{
case 1: System.out.println("Don't count on it");break;//outputs answer
