Hi Friend,

Follow these steps:

1)Create folder named form in C:/Examples/ folder.

2)Create a java class Calculate inside the form folder:

package form;
public class Calculate
{
public int a;
public int b;

public int add(int a,int b){
    return a+b;
}
}

3)Now to check this, create another class CallClass inside the Examples folder that will call the Calculate class.

public class CallClass{
    public static void main(String[] args) 
    {
        form.Calculate c=new form.Calculate();
        System.out.println(c.add(5,6));
    }
}

4)Compile the Calculate and CallClass class with the following statements:

C:\Examples\form>javac Calculate.java
C:\Examples>javac CallClass.java
C:\Examples>java CallClass

Thanks
