Question

What will be printed out as a result of the following code execution?


public class TheLoop {
    public static void main(String...args) {
        int i = 1;
        do while(i < 1)
            System.out.println("i = " + ++i);
        while (i > 1);
    }
}

Absence of braces complicates the understanding of the source code. Let's add them:


do {
     while (i < 1) {  // false when i = 1
         System.out.println("i = " + ++i);
     }
} while (i > 1);  // false when i = 1

Now it is obvious that the program will be executed successfully, but nothing will be printed out.
