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;
}
}

- Provide a detailed explanation of the architecture on the diagramarrow_forwardhello please explain the architecture in the diagram below. thanks youarrow_forwardComplete the JavaScript function addPixels () to calculate the sum of pixelAmount and the given element's cssProperty value, and return the new "px" value. Ex: If helloElem's width is 150px, then calling addPixels (hello Elem, "width", 50) should return 150px + 50px = "200px".

In the second blank, enter the array contents after one more partition of the left-hand subarray resulting from the first partition. In the third blank, enter the array contents after one more partition of the right-hand subarray resulting from the first partition. Print the numbers with a single space between them.
