Question 1
What is displayed by the following code?
String[] tokens = "A,B;C;D".split("[,;]");
for (int i = 0; i < tokens.length; i++)
| | System.out.print(tokens[i] + " "); |
◦ A,B;C;D
◦ A B C D
◦ A B;C;D
◦ A B C;D
Question 2
Analyze the following code.
class Test {
public static void main(String[] args) {
| | StringBuilder strBuf = new StringBuilder(4); |
| | 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.
