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

1. Compile and execute this program. Attach the execution results in Moodle
2. 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]);

}

} }
