loops

Hi,
Could any of you help me in easiest way of cracking loops.
I am very confused.
I post some of the example questions below:

Question 16
class JMM110 {
  public static void main (String[] args) {
    int j = 0;
    do for (int i = 0; i++ < 2 :wink: 
      System.out.print(i);
    while (j++ < 2);
}}
 
What is the result of attempting to compile and run the program? 
 
a.  Prints: 0001 
b.  Prints: 012 
c.  Prints: 012012 
d.  Prints: 012345 
e.  Prints: 001122 
f.  Prints: 1112 
g.  Prints: 111222
