How to write a program using SWITCH that accepts input from the user and that input can be used to compute the users age?

Question

This is my code:

import java.util.Scanner;

public class OctoberAge
{
public static void main(String[] args)
{

// Accept input from the user and that input can beused to compute the users age.

// if the age is less than 10 months old, you're an infant.

// 10 months - 2 years old = you're a baby

// 3 - 15 years old = you're a kid

// 16 - 18 years old = you're a teenager

// 19 - 99 years old = you're an adult

// 100 - 100+ years old = you're dead

Scanner sc = new Scanner(System.in);

int UserYear;
int UserMonth;
int a;

System.out.println("Please input your year of birth: ")

System.out.print("Year: ")
UserYear = sc.nextInt();

a = (2018 - UserYear);
System.out.println("Your age is" + a);

switch(a)
{

case 1: System.out.println("you're a baby")
break;

case 2: System.out.println("you're a kid")
break;

case 3: System.out.println("you're a teenager")
break;

case 4: System.out.println("you're an adult")
break;

case 5: System.out.println("you're dead")
break;

Answer 1

if (age < 3) {
//...
} else if (age < 16) {
//...
} else if (...) {
//...
}

Answer 2

my code is not right but can someone help me with this? need some help for a fellow beginner programmer.

Answer 3

i guess i dont fit in programming :< Its so damn hard.

Answer 4

Make sure every statement ends with a semicolon.

Other than that, I don't see any dramatic mistakes. It's just that you can't use a switch statement to check for a range of numbers. Right now, you're checking if a is 1 or 2 or 3 etc., but you want to know if it is less than 2 (infant), between 3 and 15 (kid) etc. I think the closest you can get using a switch statement would be something like

switch (a) {
case 0:
case 1:
case 2:
// infant
break;
case 3:
case 4:
//...
case 15:
// kid
break;
}

You would basically need to do that 100 times in a row to check all possible numbers.

I think a nested if else works better in your case.

This is hard.
