What will be the output of the program? public class Delta { static boolean foo(char c) { System.out.print(c); return true; } public static void main( String[] argv ) { int i = 0; for (foo('A'); foo('B') && (i < 2); foo('C')) { i++; foo('D'); } } }

'A' is only printed once at the very start as it is in the initialisation section of the for loop. The loop will only initialise that once.

'B' is printed as it is part of the test carried out in order to run the loop.

'D' is printed as it is in the loop.

'C' is printed as it is in the increment section of the loop and will 'increment' only at the end of each loop. Here ends the first loop. Again 'B' is printed as part of the loop test.

'D' is printed as it is in the loop.

'C' is printed as it 'increments' at the end of each loop.

Again 'B' is printed as part of the loop test. At this point the test fails because the other part of the test (i < 2) is no longer true. i has been increased in value by 1 for each loop with the line: i++;

This results in a printout of ABDCBDCB
