reached end of file while parsing

**JosAH** · Jul 17 '07, 04:02 PM

There's a whole lot wrong with your program. The syntax of a switch statement
is like this:

[code=java]
switch (<integer expression>) {
case <integer constant expression>: <statements>
...
case <integer constant expression>: <statements>
default: <statements> // but 'default is optional
}
[/code]

But the worst error is: you can't switch on a float type (a name?). You have
to redesign the whole lot. And where do these Jims, Kens, Marys come from?

kind regards,

Jos

                    break;
            
            switch (name) {
                case Leo:
                    System.out.println ("I.D. 0104790(M)  SURNAME MIfsud GROUP NO 2");

            default:
                System.out.println("Invalid name");
        }
   [B] }[/B]

the error is on the last bold bracket

Hello, and welcome to TSDN. First of all, from now on if you could please try and put your code in code tags (look on the right when you're posting to the box that says "REPLY GUIDELINES").

Now, I don't know if this is the exact problem, but I know it is one that needs fixing, this line:

Code:

float  name = Keyboard.readInt();

That should be readFloat() right ...? Also, when are you instantiating your scanner keyboard... I don't see it. Is this really the only error you're receiving?

OH OH, I found your problem. I'm almost 100% sure it says this when you have not closed your brackets properly. Add another bracket on the bottom there ok... try that. If not, count your brackets again, there should be an exact number of pairs, one close bracket for each open...

Hope that helped,

hi i'am an absolute beginner in programming. I am trying to create a database program for my school project which I urgenty need. the program is a database which when i input names it gives me information (Surname, I.D. no Group ) about the person.Could you please guide me through the writing of this program.thanks

Try a Properties object first. You can have a little text file that looks like this:

Code:

Ryan= I.D. 0569290(M) SURNAME Mifsud GROUP NO 1
Robert= I.D. 086790(M) SURNAME Vella GROUP NO 3
Victor= I.D. 0548790(M) SURNAME Cassar GROUP NO 5
Jim= I.D. 0971790(M) SURNAME Dimech GROUP NO 8
Sam= I.D. 0321790(M) SURNAME Muscat GROUP NO 10

etc. etc. A Properties object can read itself given an InputStream. First check
out the "article index" post in the Java Articles section. At the end of that
article you can find a link where you can download the complete API documentation
for all the Java core classes. Please download the stuff and read all about the
Properties class.

kind regards,

Jos

Hold up there man. Take this one step at a time. Split this into as many tiny parts you have to understand and come up with. What do you know/have done before and what do you not have a clue about? Do you need to make it as complex as you're making it? The old saying comes to mind: "keep it simple stupid". Just keep it simple, step by step, we can get through this.

-So you're going to input names, first get that down pat. Write a program that asks the user for a name, then prints it to the screen.

-Next, go to sun's tutorial website and take some tutorials on using databases (not an easy step, but you need it if you want to tackle databases)

-Then write a program that simply spits out info from the database.

-Then write a program that asks a user for something and prints the info.

It should be even more steps, but you get the picture...

Good luck,

Why are you asking us?

am I using a good method ??

Method to do what? Design a program that involves a database and information retrieval? Which method are you talking about?

Don't think about that for now, you can't use a switch statement for your purposes.

which statement in your opinion should i use??if you are saying switch is not good ??

**JosAH** · Jul 17 '07, 05:08 PM

Don't think about that either; as blazedaces suggested: try to read a name from
somewhere and echo it back on the screen. Try to accomplish that first. Better
take a lot of baby steps you *do* understand instead of one big step that baffles
you. You have to learn how to walk before you can run; really.

kind regards,

Jos

You technically could use a switch statement, but a switch is always of either an integer, or a character. It can not be of a string or a float.

You technically could make an array of strings, then when you ask the user for a name (Which I'm assuming you want the name to be a string, so you should be doing "String" name = keyboard.read() or something like that...) you could search for it in your array and then use a switch of the index (location in the array) where that string is stored. Then spit out the data.

I'm going to have to say though, this is unnecessarily complex. It doesn't need to be. Re-evaluate.

What EXACTLY do you need to do? It's a school project right? What are the specific requirements (you don't need to tell me, just think about it again). Maybe you don't need a database. Maybe you don't need a switch statement. Think about what you need and think of another solution...

Good luck

1. You want a string name not an integer.
Use String name = Keyboard.readLi ne();
or readString()
depending on what Keyboard class you are using.

2. You cannot switch on a string. Unfortunately you'd have to use if/else statements. eg.
if (name.equals("J onathan")) {
// some action
} else if (name.equals("J immy")){
// some other action ..
} ...

3. For string comparison you have to use .equals() as opposed to == operator.
