Both of the following occur.
C. AB CD EF
B. Runtime Error
Another index out of bounds
This is another example of a program that throws an index out of bounds exception. In this case, since the container is an array object, the name of theexception is ArrayIndexOutOfBoundsException .
Populate a three-element array object
The code in the following fragment creates and populates a three-element array object containing reference to three String objects.
void doIt(){
String[]ref = {"AB ","CD ","EF "}; Access an out-of-bounds element
The next fragment attempts to access elements at indices 0 through 3 inclusive.
for(int i = 0; i<= 3; i++){
System.out.print(ref[i]);
}//end forloop Since index value 3 is outside the bounds of the array, the program throws the following exception and aborts:
AB CD EF
java.lang.ArrayIndexOutOfBoundsExceptionat Worker.doIt(Ap150.java:22)
at Ap150.main(Ap150.java:14) Note however that the program displays the contents of the three String objects referred to by the contents of the first three elements in the array before the problem occurs.
That's the way it often is with runtime errors. Often, a program will partially complete its task before getting intotrouble and aborting with a runtime error.
