Chapter 6, Problem 3E

Explanation of Solution

Program code:

Test.java

//import the required packages

import java.io.File;

import java.util.Arrays;

import java.util.Scanner;

//define a class inputStats

public class Main

{

//define the main

public static void main(String[] args) throws Exception

{

//create the object of File class

File fileName = new File("file.txt");

//create the object of Scanner class to refer the file

Scanner in = new Scanner(fileName);

//call the method negativeSum()

negativeSum(in);

}

//define a method negativeSum()

public static boolean negativeSum(Scanner in)

{

//declare the integer variables "step" and "sum"

int step =0;

int sum = 0;

//declare a boolean variable flag

boolean flag = false;

//iterate a while loop to get the integers

while (in.hasNextInt())

{

//add the tokens to sum

sum+= in.nextInt();

//increment the step by 1

step++;

//if the value of sum is less than 0

if (sum < 0)

{

//set the value of flag as true

flag = true;

//break the condition

break;

}

}

//if the value of flag is true

if (flag)

{

//print the value of sum and step

System.out.println(sum + " after " + step + " steps");

}

//if the value of flag is false

else

{

//print the statement

System.out.println("no negative sum");

}

//return the value of flag

return flag;

}

}

Explanation:

The above snippet of code is used find the negative sum of the values in the given input file...
