When is while(true) true, and when is it false?
It’s always true, it’s never false.
Some people use while(true)
loops and then use break
to exit them when a certain condition is true, but it’s generally quite sloppy practice and not recommended. Without the use of break
, return
, System.exit()
, or some other such mechanism, it will keep looping forever.
