    Default java package problem

    //india.java
    package mtv;
    class india{
    public void file(){
    System.out.println("hellooo");
    }
    -------------------------------------------------------
    //chair.java
    package web;
    import mtv.*;
    class chair
    {
    public static void main(String a[])
    {
    chair c= new chair();
    c.file();
    }

    package mtv doesnot exist
    Where is the package mtv located when you compile the program? Can the javac program find it?
    Is its definition on the classpath?

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Package "mtv" contains a single class, "india". (BTW, please use Initial capitals for classnames.)

    In package "web" you declare a single class "chair", and import "mtv". But you never use a _class_ definition from mtv. Rather, you instantiate an object of the type you haven't finished defining yet, and then invoke file(), which does not exist (in class "chair").

    There are a number of problems here, and you need to solve them to even get to the point where the import of mtv makes sense.

    - You need to consider the access modifiers for india class so other classes can see it.
    - You need to fix your main() method so it actually uses the india class to get access to file() [if this is your intention; this is unclear]

    Taking the time to learn and leverage an IDE like Eclipse or NetBeans will show you all the places your current code is syntactically and structurally incorrect.
