Type Sum, Summation and Driver classes given in the textbook, page 164 test the code with three integer values, take a screen shot of all three output in one image. zip .java files and the image

class Sum

{

}

private int sum;

public int getSum() {

return sum;

}

public void setSum(int sum) {

this.sum sum;

}

class Summation implements Runnable

{

}

private int upper;

private Sum sumValue;

public Summation(int upper, Sum sumValue) {

this.upper = upper;

this.sumValue = sumValue;

}

public void run() {

int sum = 0;

}

for (int i = 0; i <= upper; i++)

sum += i;

sumValue.setSum(sum);

public class Driver

{

}

public static void main(String[] args) {

if (args.length > 0) {

}

if (Integer.parseint(args[O]) < 0)

System.err.println(args[O] + "must be>= 0.");

else {

II create the object to be shared

Sum sumObject = new Sum();

int upper= Integer.parseint(args[O]);

Thread thrd =new Thread(new Summation(upper, sumObject));

thrd.start();

try {

thrd. join () ;

System.out.println

("The sum of "+upper+" is "+sumObject.getSum());

} catch (InterruptedException ie) { }

}

else

System.err.println("Usage: Summation "); }
