    Default call() is not public in BTEST, cannot be accessed by outside package

    Hello All,
    I have an issue. I created 2 java programs, a.java and b.java

    content of a.java:

    package test;
    import test1.*;
    publuc class ATEST {
    public static void main (String[] args) {
    BTEST.call();
    }
    }

    content of b.java:

    package test1;
    public class BTEST {
    string name;
    void call() {
    .
    .
    }
    }

    Getting call() is not public in BTEST; cannot be accessed by outside package.

    Question is b.java must be declared in this fashion. I need to add access modifiers so that call() and any constructors are the only things that are accessible from other packages. Any other method can only be accessed from the BTEST class.

    Your kind assistance would be greatly appreciated.

    Thanks,

    call() is not public in BTEST; cannot be accessed by outside package.
    Why not make it public if you want to call it?

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]

    You don't know how to make a method public?

    Then you need to fix this error. Don't try to call the method without first creating an object of the class to call the method on.

    I'm not ignoring anything. Here and I'll try again! Why would you need it in this fashion to begin with?

    Sorry. Here you go.

     public void call() {
     System.out.println ("Some text.....");

    - non-static method call() cannot be referenced from a static context
    Did you read the tutorial? Do you have any questions about what you read?


    Why are you coding this statement: BTEST.call();

    I'm calling it because I need to print some values.

    Sorry, I meant to ask: Why did you code the statement the way it is coded?
