Answer 1

Answer:

numPeople +=5;

Explanation:

The statement numPeople +=5; increases the value of the variable numPeople by 5, this statement is equivalent to writing numPeople = numPeople +5. As a matter of fact another way of accomplishing this is shown in the code below were we carry out the increament by 5 inside the print statement. See line 7 of the code below.

1. import java.util.Scanner;
2. public class AssigningNumberToVariable {
3. public static void main (String [] args) {
4. int numPeople = 0;
5. numPeople = 10;
6. System.out.print("There are ");
7. System.out.print(numPeople+5);
8. System.out.println(" people.");
9. return;
10. }
11. }
