Given the following code, which statement is true?

class MyClass
{
public static void main(String[] args)
{
int k = 0;
int l = 0;
for (int i=0;i<=3;i++)
{
k++;
if (i==2) break;
l++;
}
System.out.println(k+", "+l);
}
}
(a) The program will fail to compile
(b) The program will print 3, 3 when run
(c) The program will print 4, 3 when run if break is replaced by continue
(d) The program will fail to compile if break is replaced by return
(e) The program will fail to compile if break is simply removed.

Final answer:

The statement that is true regarding the given code snippet from a Computers and Technology perspective is option (c), indicating that if the 'break' is replaced with 'continue', the program will print the values '4, 3'.

Step-by-step explanation:

The code provided falls under the subject of Computers and Technology and is typically suited for a High School level student learning about programming constructs. Analyzing the given code snippet:

class MyClass{
public static void main(String[] args) {
int k = 0;
int l = 0;
for (int i=0;i<=3;i++) {
k++;
if (i==2) break;
l++;
}
System.out.println(k+", "+l);
}
}

We can deduce the following:

  • Option (a): The program will compile successfully; therefore, option (a) is false.
  • Option (b): When running the program, the for loop iterates until i equals 2, at which point the break statement is executed. Hence, the value of k will be 3 and the value of l will also be 2 (not 3), so option (b) is false.
  • Option (c): If the break is replaced by continue, the loop will skip the increment of l when i is 2 but will continue looping. Thus, k will end up with a value of 4 and l will remain at 2, which makes option (c) true.
  • Option (d): Replacing break with return will not cause a compilation failure; the function will simply return prematurely. So option (d) is false.
  • Option (e): If the break is removed, the program will still compile. The values for k and l will both end at 4 since no statement will interrupt the loop prematurely. Thus, option (e) is false.

The accurate statement is option (c): The program will print 4, 3 when run if break is replaced by continue.
