Consider the statement below:
StringBuilder sb1 = new StringBuilder("a toyota");
Which of the following creates a String object with the value "toy"?
A) String res = sb1.subString(2, 5);
B) char dest[] = new char[sb1.length()]; sb1.getChars(2, 5, dest, 0);
String res = new String(dest);
C) char dest[] = new char[sb1.length]; dest = sb1.getChars(2, 5);
String res = new String(dest);
D) char dest[] = new char[sb1.length()]; dest = sb1.getChars(0, 3);
String res = new String(dest);

Quizplus · Accepted Answer

Option B is correct because it uses the `getChars` method to extract characters from index 2 to 5 from the `StringBuilder` object `sb1` and stores them in the `dest` array. Then, it creates a new String object `res` with these characters. Note that the `getChars` method copies characters into the destination array starting at the specified destination offset, which is correctly set to 0 in this case. The other options are incorrect due to syntax errors or not correctly extracting the substring "toy".
