Convert int to a bool
How do I make this work?
int i = 0; do { System.out.println("blah blah blah"); Scanner input = new Scanner(system.in); i = input.nextInt(); if (i != 0) i = 1 } while (i);
I want the program to say "okay, this 'i' is a 1, so that means TRUE, so we'll keep going" or "nope, this 'i' is a 0, that's FALSE, so let's exit the loop".
It seems really hard?

Re: Convert int to a bool
A boolean expression can be expressed like this:
i==0
i<76
i!=17
etc.
These evaluate to a boolean value (true or false). You can use boolean values in things like if statements and while loops.
You've already used a boolean expression in an if statement. You say you want to use a boolean expression in a while loop. What part of that is confusing you?

Re: Convert int to a bool
I guess I'm just used to C++ where you could say 'while(integer)'
I feel like that's cleaner than always saying 'while (integer == 1)'.....
Re: Convert int to a bool
I guess it's a personal preference, but while(i == 1) seems fine to me. In fact I would say it's better than just while(i) because it makes it clear that 1 is the only value it should continue for.
For your code, I don't know why you're checking if(i != 0) and making it 1. That step becomes unnecessary if you just use while(i != 0) instead.
