Question

Consider the following code snippet:public static void check(ArrayList chknum1){ int cnt = 0; for(int i = 0; i < chknum1.size(); i++) { if(chknum1.get(i) == 0) { cnt++; } } System.out.println("The total 0 values in the list are: " + cnt);}Which one of the following is true about the check method in the given code snippet?Select one:a. The check method counts all the elements with value 0 in an array list passed as a parameter to the method.b. The check method removes all the elements with value 0 from an array list passed as a parameter to the method.c. The check method counts all the elements with value 0 in an array list passed as a parameter to a method and also returns the count.d. The check method adds 0 to the elements of an array list as a parameter to a method and also returns the array list.

Answer 1

The answer to this question is "option a".

Explanation:

• In the given question a method is defined that is "check" this method accepts the array list as a parameter and does not return any value because its returns type is void.

• Inside a function, we define an integer variable that is "cnt" and define a loop inside a loop we use conditional statement in the if block we check array list object value is equal to 0. If this condition is true it will print cnt value.

• In this question accept option A, all other options are wrong because these options will not count all array elements.
