Given:
01. public class TestString3 {
02. public static void main(String[] args) {
03. // insert code here
04. System.out.println(s);
05. }
06. }
Which two code fragments, inserted independently at line 3, generate the output 4247? (Choose two.)
A. String s = "123456789";
s = (s-"123").replace(1,3,"24") – "89";
B. StringBuffer s = new StringBuffer("123456789");
C. delete(0,3).replace(1,3,"24").delete(4,6);
D. StringBuffer s = new StringBuffer("123456789");
E. substring(3,6).delete(1,3).insert(1, "24");
F. StringBuilder s = new StringBuilder("123456789");
G. substring(3,6).delete(1,2).insert(1, "24");
H. StringBuilder s = new StringBuilder("123456789");
delete(0,3).delete(1,3).delete(2,5).insert(1, "24");
