It seems like I never ever got the right answer for this kind of problems, could anyone please explain step by step to me?
30. Consider the code fragment below:
outer: for( int i = 1; i <3; i++ )
{ inner: for( j = 1; j < 3; j++ )
{ if( j==2 )
continue outer;
System.out.println( "i = " +i ", j = " + j );
}
}
Which of the following would be printed to standard output?
a) i = 1, j = 1
b) i = 1, j = 2
c) i = 1, j = 3
d) i = 2, j = 1
e) i = 2, j = 2
f) i = 2, j = 3
g) i = 3, j = 1
h) i = 3, j = 2

HI!
1.outer: for( int i = 1; i <3; i++ )
2. { inner: for( j = 1; j < 3; j++ )
3. { if( j==2 )
4. continue outer;
5. System.out.println( "i = " +i ", j = " + j 6. );
7. }
8. }
In the above code, the variable i takes the values:1 and 2. Simmilarly, the variable j takes its values as 1 and 2.
Now acording to the code, when the value of j is equal to 2, the outer loop is continued. So the answers are options a and d, as the starting value of both i and j is 1 and that is printed, then the value of i and j becomes 2, so here the line 4 comes into play as j equals to 2 and the inner loop is abandoned. So there are only two correct answers- a and d.
I hope this helps,
Rachel.

1.outer: for( int i = 1; i <3; i++ )<br /> 2. { inner: for( j = 1; j < 3; j++ )<br /> 3. { if( j==2 )<br /> 4. continue outer;<br /> 5. System.out.println( "i = " +i ", j = " + j 6. );<br /> 7. }<br /> 8. }<br /> 9.<br /> here we can go line by line execution of this code<br /> line 1 --> i = 1 as less than 3 goes to line 2<br /> line 2 --> j = 1 as less than 3 goes to line 3
line 3 --> false goes to line 5
line 5 prints 1,1 goes to line 2 again ( here u get he print ans (a))
line 2 --> j = 2 as less than 3 goes to line 3
line 3 --> true goes to line 4
line 4 --> goes to line 1 with continue so the value of i will continue with the next iteration and the inner loop is finished
line 1 --> i = 2 as less than 3 goes to line 2
line 2 --> j = 1 as less than 3 goes to line 3
line 3 --> false goes to line 5
line 5 prints 2,1 goes to line 2 again ( here u get he print ans (d))
line 2 --> j = 2 as less than 3 goes to line 3
line 3 --> true goes to line 4
line 4 --> goes to line 1 with continue so the value of i will continue with the next iteration and the inner loop is finished
line 1 --> i = 3 as its not less than three the loop terminates and comes to line 9
