ArrayTest.java(attached in Moodle) provides an example on coding array basics
- initialize an array with predetermined values
- access array elements, and
- stay within the bounds of an array
- Compile and execute this program. Attach the execution results in Moodle
- Explain in your words the reason for the exception encountered
public class ArrayTest
{
public static void main(String args[])
{
// 1.declare an array
double target[] = new double[3];
double source[] = {1.0, 5.5, 7.9};
int loopIndex;
// 2.initialize the array - Copy values from source to target.
for(loopIndex = 0; loopIndex < 3; loopIndex++)
target[loopIndex] = source[loopIndex];
// 3.Assign values to two elements of target.
target[0] = 2.0;
target[1] = 4.5;
// Print values stored in source and target.
for(loopIndex = 0; loopIndex < 3; loopIndex++) {
System.out.println("Source " + source[loopIndex]);
System.out.println("Target " + target[loopIndex]);
}
// 4.Encounter ArrayException due to change loopIndex <= 3
System.out.println("======== ARRAY EXCEPTION BELOW ==========");
for(loopIndex = 0; loopIndex <= 3; loopIndex++)
{
System.out.println("Source " + source[loopIndex]);
System.out.println("Target " + target[loopIndex]);
}
} }
