Thread: unreachable statement Again?

    public static void main(String[] args) {
 
        long targetNumber,
             guessNumber;
 
        targetNumber = 34;
        System.out.println("Target Number Is:  " + targetNumber);
 
        do {
 
           guessNumber = (int) (Math.ceil(Math.random() * 100));
           System.out.println("Guess Number Is:  " + guessNumber);
        }
        while (true);
 
        if (guessNumber == targetNumber) {   // my compiler is displaying this part as "Unreachable statement"
 
            System.out.println("\n");
            System.out.println("Match Number Is:  " + guessNumber);
            System.exit(0);
        }
    }
}

 if (guessNumber == targetNumber) {   // my compiler is displaying this part as "Unreachable statement"

why?

When do you think your code will get past this do while loop?

       do {
 
           guessNumber = (int) (Math.ceil(Math.random() * 100));
           System.out.println("Guess Number Is:  " + guessNumber);
        }
        while (true);

// Json

}

 if (guessNumber == targetNumber) {   // my compiler is displaying this part as "Unreachable statement"

why?

it is a infinite loop. control never come out of do while loop upto stack overflow

ahh ok ok.. its an infinite loop.The program will only read and stay at the loop's body..
and it wont have any chance to execute or to reach the following statements after it because it will loop forever...
