[feda]

Hi everybody,
I am new to java I installed netbeans 6.0.1
I tried running the following simple program but it didnor work???


import java.util.*;
public class Hello
{
public static void main(String [] args)
{
Scanner reader = new Scanner(System. in);
String name;

System.out.prin t("What is your name? ");
name = reader.readLine ();

System.out.prin tln(name + " I look forward to a long and fruitful relationship.") ;
}
}

I got the following error:

init:
deps-jar:
Compiling 1 source file to C:\Documents and Settings\PAAET User\My Documents\NetBe ansProjects\Jav aApplication8\b uild\classes
C:\Documents and Settings\PAAET User\My Documents\NetBe ansProjects\Jav aApplication8\s rc\javaapplicat ion8\Main.java: 28: class, interface, or enum expected

Try using this code to read the name

name= scanner.next();

The class you have shown us is not the class that was compiled.

If you are new to Java, I suggest ignoring Netbeans and all such IDEs for now and working with simple text editors like Notepad or Textpad until you've grasped the basic concepts.

I ran the program ad I got the following error:

init:

name =Scanner.nextLi ne();

reminding my code program is:

package javaapplication 8;

/**

import java.util.*;
public class Hello
{
public static void main(String [] args)
{
Scanner reader = new Scanner(System. in);

name =Scanner.nextLi ne();

System.out.prin tln(name + " I look forward to a long and fruitful relationship.") ;

You put your code in a file with a wrong name. A public class Foo has to be
stored in a file name Foo.java. You put a public class Hello in a file named
Main.java. Also you have a Scanner instance 'reader'; that instance has a
method nextLine() and that method isn't static so you can't call it on the class
Scanner.

Thankyou very much for ur answer which one error has solved but what is the solution to the second error?? is there another static method ?

You created a 'reader' object that can do the job for you so don't call Scanner.readLin e()
but reader.readLine ()

I changed my code as follows:

[code=java]
import java.lang.*;
import java.io.*;
public class Main
{
public static void main(String [] args)
{

String name;

System.out.prin t("What is your name? ");
BufferedReader reader=new BufferedReader (new InputStreamRead er(System.in));
name =reader.readLin e();

System.out.prin tln(name + " I look forward to a long and fruitful relationship.") ;
}
}
[/code]

But still not working I got the following error:

init:
deps-jar:

No need to say sorry; you should read some tutorials first before you start coding
by just guessing. btw I still don't understand that line number 23 in the error
diagnostic message; your source file doesn't have that many lines. The way
you're reporting your problem is very confusing. For now change your line
where you defined your main method to:

[code=java]
public static void main(String[] args) throws IOException {
[/code]

Note that this is not a proper solution but it helps you to get started with your
first program. Please read the API documentation for the classes and their methods.

I read tutorials but the problem that I studied Pascal at my college which is much easier. So please be patient with me.

You're still not showing us the code you are compiling: manually counting your
main() method starts at line 10 while the compiler finds it at line 15. The code
you're showing us includes the java.io.* entire package. That IOException is
a member of that package. I don't understand what you're doing, sorry.
