if(gender > 2){
and its associated closing brace "}"
... and try again. (You don't need it and it doesn't make sense anyway.)
The default statement(s) which you have are correct, so leave as is:
default: System.out.println("Please enter 1 or 2"); // right way to handle other input
Remove the dotted line, or comment it like so:
//-------------------
Good luck!
You can put the whole thing in a while loop and modify the condition variable in the case statments:
import java.util.Scanner;
public class UniqueFunctions {
public static void main(String[] args) {
Scanner uinput = new Scanner(System.in);
int gender;
int boy = 1;
int girl = 2;
boolean play = true;
while(play) {
System.out.println("Are you a boy or a girl? ");
System.out.println("1. Boy |" + " 2. Girl");
gender = uinput.nextInt();
switch(gender){
case 1: gender = 1;
System.out.println("You are a Boy! ");
play = false;
break;
case 2: gender = 2;
System.out.println("You are a Girl! ");
play = false;
break;
default: System.out.println("Please enter 1 or 2");
break;
}
}
}
}
I've been learning Java, and I've encountered a problem with multiple user inputs. I wrote this class to try out using multiple classes:
import java.util.Scanner;
public class UniqueFunctions {
Scanner uinput = new Scanner(System.in);
public void findgender(){
int gender;
int boy = 1;
int girl = 2;
System.out.println("Are you a boy or a girl? ");
System.out.println("1. Boy |" + " 2. Girl");
gender = uinput.nextInt();
if(gender > 2){
switch(gender){
case 1: gender = 1;
System.out.println("You are a Boy! ");
break;
case 2: gender = 2;
System.out.println("You are a Girl! ");
break;
default: System.out.println("Please enter 1 or 2");
---------------
break;
}
}
}
}
It will give me one message and then close, but I want to allow user input once again in the default case where the -------
is. How do I do this?
