Analyze the following code.

class Test {
public static void main(String[] args) {
​StringBuilder strBuf = new StringBuilder(4);
​strBuf.append("ABCDE");
​System.out.println("What's strBuf.charAt(5)? " + strBuf.charAt(5));
}
}


▸ The program has a compilation error because you cannot specify initial capacity in the StringBuilder constructor.

▸ The program has a runtime error because because the buffer's capacity is 4, but five characters "ABCDE" are appended into the buffer.

▸ The program compiles and runs fine.

▸ The program has a runtime error because the length of the string in the buffer is 5 after "ABCDE" is appended into the buffer. Therefore, strBuf.charAt(5) is out of range.
