I am currently working with a while loop and was confused as to why I couldn't end the loop.
I played around with it for a little while and for some reason the following code works and ends the while loop:
boolean keepGoing = true;
while (keepGoing != false)
{
//execute code
}
System.out.println("Would you like to continue? Enter Y for yes or N for no.");
String keepGoingYesOrNo = input.nextLine();
if (keepGoingYesOrNo.equals("Y"))
{
keepGoing = true;
matchCount=0;
guessCount=0;
}
else
{
System.out.println("Goodbye!");
keepGoing = false;
But the alternative doesn't end the while loop:
boolean keepGoing = true;
while (keepGoing = true)
{
//execute code
}
System.out.println("Would you like to continue? Enter Y for yes or N for no.");
String keepGoingYesOrNo = input.nextLine();
if (keepGoingYesOrNo.equals("Y"))
{
keepGoing = true;
matchCount=0;
guessCount=0;
}
else
{
System.out.println("Goodbye!");
keepGoing = false;
Shouldn't while (keepGoing = true) and while (keepGoing != false) be the same thing. I got the code to work but I was hoping to get some clarification on why one works and the other doesn't.

Answer 1

One thing to look out for is that (keepGoing = true) and (keepGoing == true) are not the same. If you want to check if keepGoing is true, you should use ==. When you use the single =, you're assigning true to keepGoing, so every time you're trying to check if it's true, you're actually setting it to true.
Also, because while loops are already checking if the condition is true, you could simplify your while statement to just while (keepGoing) {}.
