Question

Consider the following code segment.

int a = 1;
String result = "";
while (a < 20)
{
result += a;
a += 5;
}
System.out.println(result);
What, if anything, is printed as a result of executing the code segment?
A 21
B 161116
C 161161
D 16111621
E Nothing is printing because of an infinite loop.

Answer 1

The result of executing the code segment will print: 161116. The correct answer is: C 161161

Step-by-step explanation:

The code segment uses a while loop to repeatedly add the value of a to the result string until a is no longer less than 20. Each time through the loop, a is incremented by 5. So the value of result after the loop is finished will be 161116.

The provided Java code initializes an integer variable a to 1 and an empty string variable result. The while loop iterates as long as a is less than 20. In each iteration, the value of a is appended to the result string, and a is incremented by 5. The loop produces the sequence of values: 1, 6, 11, and 16.

The final value of result after the loop is "161161". When System.out.println(result) is executed, it prints "161161" to the console. Therefore, the correct output is option C, "161161".

The code does not result in an infinite loop, and each iteration appends the incremented value of a. The output reflects the concatenation of these values until the loop exits, providing the expected result.

The correct answer is: C 161161
