how many ways can I use a switch statement

[jaytee]

I'm trying to come up with multiple ways to use a switch statement instead of the one way that was shown in the TUT
I'm wondering if I can have the end user punch in a number and it goes exactly to the case the number that coincides with the specific case

EX:

import java.util.Scanner;
public class SwitchCase {
public static void main(String arg[]){
int Account1;
int Account2;
int Account3;
Account1 = 1441;
Account2 = 2441;
Account3 = 3441;
Scanner Info=new Scanner(System.in);
System.out.println(Info.nextLine());
switch (Account1){

case 1441:
System.out.println("Your Name is Chuck Thomas" );
break;
case 2441:
System.out.println("Your Name is James Waverly");
break;
case 3441:
System.out.println("Your name is Johnny Knoxville");
default:
System.out.println("Account not present");
break;

I want it to be possible for the user to punch in which case they want

What do you want the user to enter: The full number(4 digits) used in the switch or do you want it simpler like: 1,2, 3
You can have more than one case: statement for a block of code.

Ask the user the question, get his response as an int (or String and convert to int) and use that in the switch

[DarrylBurke]

In Java 7, you can also use Strings in a switch. The usual condition of cases being compile time constants still applies.

So I would write the cin>> like this

import java.util.Scanner
class name{
    public static void main(String arg[]){
       System.out.out.println("enter your four digit number);
          Scanner input = new Scanner (System.in);
            int Number;
              Number = (input);
               switch (Number){
case 1:

Does your code compile ok?
Before posting, you'd save some time if you'd compile it and get rid of the compiler errors before posting.
Also if you don't understand what the error message says, you could post the full text of the error message with your question.

[jaytee]

it compiles but when I enter any of the 4 digit numbers it gives me the first case only
(e.g. 2441
2441
Your Name is Chuck Thomas)
only 1441 is supposed to be Chuck Thomas

[Norm]

Please post the code that you are currently executing.

[jaytee]

This is the code I'm currently posting and it compiles, it just doesn't do exactly what I want it to do

import java.util.Scanner;
public class SwitchCase {
public static void main(String arg[]){
int Account1;
int Account2;
int Account3;
Account1 = 1441;
Account2 = 2441;
Account3 = 3441;
Scanner Info=new Scanner(System.in);
System.out.println(Info.nextLine());
switch (Account1){
 
case 1441:
System.out.println("Your Name is Chuck Thomas" );
break;
case 2441:
System.out.println("Your Name is James Waverly");
break;
case 3441:
System.out.println("Your name is Johnny Knoxville");
default:
System.out.println("Account not present");
break;

[Norm]

That code will not compile. For starters it is missing 3 ending }s

What is the value of Account1 when you execute the switch statement?
Add a println just before the switch statement to print out the value of Account1 so you can see.

[jaytee]

I hope I followed your directions right but this is what I put before the switch statement

System.out.println(Account1);
		switch (Account1){

after it compiled the screen was blank until I punched in Account1
and this is what popped up

Account1
Account1
1441
Your Name is Chuck Thomas

[Norm]

Is that the correct way for the switch statement to work when Account1 has the value: 1441?

You need to read a value in from the user and store it in Account1 to give the user control over what happens.

[jaytee]

so

import java.util.Scanner;
and
Scanner Info=new Scanner(System.in);

is not the way to read the value in?
what is the correct syntax for that code?

[Norm]

After you define a Scanner object, you must use one of the Scanner class's next... methods to read data into a variable.
Look at the API doc for the Scanner class to see which method to use.
Also there are lots of code samples on the forum. Search here for Scanner or use Google

[jaytee]

where can I find the API docs?

[Norm]

This site has doc for the SE classes:
Java Platform SE 6
Find the class in the lower left, click on it and the doc is displayed in the main window.
