The answer is correct but actually the explanation given here is wrong. Consider the loops:
Code: Select all
final int INT1=0, INT2=4;
int i=INT1;
do { System.out.println(i); }while(i++<INT2);
OR
Code: Select all
int i;
for(i=INT1; i++<INT2; System.out.println(i));
In both cases, the loops will print 1,2,3,4
and not 1,2,3 as is given in the explanation

The loor:
int i=INT1; do { System.out.println(i); }while(i++<INT2);
print: 1 2 and not 1 2 3
So I think this one is the right answer

Admin is correct. however, The problem in this questions is the explanation. It is REALLY poor/vague. So, the only chance to see whats is going on is go to the IDE, and check.

Can you please tell what is vague about the explanation so that more help can be provided?
The explanation sets INT1 and INT2 to 2 and 3 respectively and shows the outputs for all the loops given in the question. One is expected to run the loops mentally (in the exam) but while practicing one can actually put the code snippets in a class and run it like this:
Code: Select all
public class TestClass {
public static void main(String[] args){
int INT1=1 ; int INT2=3;
System.out.println("-----loop in probblem statment ----");
for(var i=INT1; i<INT2; i++){
System.out.println(i);
}
System.out.println("------option 4---");
int i=INT1;
do { System.out.println(i); } while(i++<INT2);
}
}
