What would be the results of the following code?
final int SIZE = 25;
int[] array1 = new int[SIZE];… // Code that will put values in array1
int value = 0;
for (int a = 0; a < array1.length; a++)
{
value += array1[a];
}
final int SIZE = 25;
int[] array1 = new int[SIZE];… // Code that will put values in array1
int value = 0;
for (int a = 0; a < array1.length; a++)
{
value += array1[a];
}
a.
Value contains the highest value in array1.
b.
Value contains the lowest value in array1.
c.
Value contains the sum of all the values in array1.
d.
This would cause the program to crash.
