What is the final value of s3 in the following?

String s1 = "Mt.";

String s2 = "St. Helens";

String s3 = s1 + s2;

s2 = "Rainier";
  1. "St. Helens"
  2. "Rainier"
  3. "Mt.St. Helens"

What is the value printed by the following?

int[] nums;  //line 1

nums[0] = 10; //line 2

nums[1] = 11; //line 3

nums[0] = nums[1]; //line 4

System.out.println(nums[0]); //line 5
  1. 10
  2. 11
  3. won't get to line 5 because of a compile error on line 2
  4. won't get to line 5 because of a run-time error on line 2
Some compilers will give you an error: "local variable may not have been initialized." If not, then there would be a run-time error.

StudentData stu; //line 1

stu = new StudentData("Rodney", 03277); //line 2

boolean enrolled = stu.checkStatus();  //line 3

stu.printout(); //line 4

  1. Which line or lines contain a declaration? __1, 3
  2. Which line or lines create an object? ___2
  3. Which line or lines send a message to an object? __3, 4.  2 won't be scored incorrect, although technically there is no object to send a message to until after the constructor has executed.
