East Carolina University (ECU)Computer Science
Prof. Ronnie W. Smith

The solution to a java code execution problem where the input values from the user are given and the task is to determine the stored values in the variables. The code segment involves using a scanner object to read user input and assign values to variables n1, n2, and n3, which are initially declared as integers, and a string variable s1. The user input is given as 28 33 44 112 1798 245 5.

1. Consider the following Java code segment
int n1, n2, n3;
String s1;
Scanner keyboard = new Scanner(System.in);
n3 = keyboard.nextInt();
s1 = keyboard.nextLine();
n2 = keyboard.nextInt();
n1 = keyboard.nextInt();
n3 = keyboard.nextInt();
Suppose also that the following input is typed in at the keyboard:
28 33 44
112
1798 245
5
What will be the values stored in the variables if the code segment is executed
using the given keyboard input? Where you see whitespace on a line, assume it
is exactly one space.
