| What is the length of the string below?<br>String str = "Java Program"                                                                                                                                                                                                                      | 12               |
| With str as defined above, give a call to the substring method that returns the substring "gram".                                                                                                                                                                                           | str.substring(8) |
| Use the string concatenation operator to change the string variable str to contain the string "Java Programming".                                                                                                                                                                           | str += "ming"    |
| What does the following statement sequence print?<br><br>String str = "Harry";<br>int n = str.length();<br>String mystery = str.substring(0, 1) + str.substring(n - 1, n);<br>System.out.println(mystery);                                                                                  | Hy               |
| Consider the following statement sequence. If the user provides the input John Q. Public, what is printed? If an error occurs, type error.<br><br>Scanner in = new Scanner(System.in);<br>String first = in.next();<br>String last = in.next();<br>System.out.println(last + ", " + first); | Q., John         |
