Question

consider the following java code and console screenshot:
java code:
import java.util *;
public class scannerinput{
public static void main(string args){
int a, b;
string first, last;
scanner input = new scanner(system.in);
system.out.print(\enter name and age: \);
first = input.next();
b = input.nextint();
system.out.println(first + \ you are \ + b);
}
}
console screenshot:
which of the following represents the output when the user hits enter?
reilly you are 25
25 you are reilly
reilly 25 you are

Explanation:

Step1: Analyze next() method

The next() method in Java's Scanner class reads input until the next whitespace. So if the user enters "Reilly 25" (assuming Reilly is the name and 25 is the age), first = input.next() will assign "Reilly" to the first variable.

Step2: Analyze nextInt() method

The nextInt() method reads an integer. So b = input.nextInt() will assign 25 (the integer part of the input) to the b variable.

Step3: Analyze the println statement

The System.out.println(first + " you are " + b); statement will concatenate the first (which is "Reilly") and b (which is 25). The format is first + " you are " + b, so it will print "Reilly you are 25".

Answer:

Reilly you are 25
