Exam Code: 1Z0-803
Exam Name: Java SE 7 Programmer I
A method doSomething () that has no exception handling code is modified to trail a method that throws a checked exception. Which two modifications, made independently, will allow the program to compile?
B. Declare the exception to be thrown in the doSomething() method signature.
C. Cast the exception to a RunTimeException in the doSomething() method.
D. Catch the exception in the method that calls doSomething().
Given the code fragment:
String color = "Red";
switch(color) {
case "Red":
System.out.println("Found Red");
case "Blue":
System.out.println("Found Blue");
break;
case "White":
System.out.println("Found White");
break;
default:
System.out.println("Found Default");
}
What is the result?
B. Found Red
Found Blue

E. The third argument is given the appropriate false value for its declared type.
F. An exception occurs when the method attempts to access the third argument.
Given the fragment:
int [] array = {1, 2, 3, 4, 5};
System.arraycopy (array, 2, array, 1, 2);
