Exercise 3:
The following code asks a user to enter her/his age then determines if a user is an adult or not. Trace the code, to find and solve the syntax errors. You need to identify the errors and rewrite the correct code.
import java.util.Scanner;
public class Ex3 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter your age:");
int age = input.nextInt();
double flag = isAdult(double age);
if(flag) {
System.out.println("You are an adult.");
} else {
System.out.println("You are not an adult.");
}
}
public boolean isAdult(int age) {
if(age > 18) {
return true;
} else {
return false;
}
}
}
Exercise 4:
