Question

When a Java method is passed an array as a parameter, how does the method know how many elements the array has?

1.The method can use the length member of the array object to find out the number of elements.

2.The size of the array must be passed as a separate parameter to the method.

3.The method can simply ask the user for the size of the array.

4.The method has no way of knowing since it did not create the array.

1.When there are no references to the object left in the program.

2. When the programmer deletes the object.

3. When the object tells the JVM its time to die.

4. When the program is finished, all dynamically allocated objects are reclaimed.

When is the memory space for dynamically allocated objects reclaimed by the JVM?
