    Default calling a method into System.out.print() method????? solved

    is it possible to call a method into another method?


    i can see the error into my code and it's not possible for me to call range() into System.out.print() function.


    if possible give me a solution here.



    public class Main {

    public static void main(String[] args) {

    A obj1=new A();
    System.out.println("The value of x from the class A is "+obj1.x);
    System.out.println("The value of y from the class A is "+obj1.y);
    obj1.range();
    System.out.print(obj1.range()); // error shows here. it's not executed . method calling method.
    }
    }

    class A{

    int x=2,y=7;
    public void range()
    {
    int z=x*y;

    }
    }

    Default Re: calling a method into System.out.print() method?????

    Using a method call as part of a String requires that the method return a value.
    range is void so the compiler can not get any value to convert and add to the String.

    When I compile your code I get this error message:
    error: 'void' type not allowed here
    Please edit your post and wrap your code with code tags:

    [code]
    **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.
