Hi Sam,

Yes! you are right!! I didn't see the section. Usually the .net developers asks more questions in this forum.

Since i am new new contributor to the forum, not aware the such things.

let me see the section before answering the questions..... But the java/C# concept wise almost same... but the question was also not clear. he wants to call the parent static method from the inherited child class method or if static method in the parent class is accessible when another child class inherits...

Senthilkumar, I know you have not been active in the forums much. It helps to look at the top left of threads to see what forum a thread is in. It helps to do that sometimes but not always. Since this thread, as Vulpes indicates, is in the Java forum, it helps to know this is a Java question.

The question is actually about Java rather than .NET but I don't understand it anyway :(

If you're asking whether a derived class inherits its parent's static methods, the answer is that it does and can access them as long as they're not private.

The following program prints Hello World twice:

import java.io.*;

class Parent
{
public static void PrintMessage()
{
System.out.println("Hello World");
}
}

class Derived extends Parent
{
}

class Test
{
public static void main(String[] args)
{
Parent.PrintMessage();
Derived.PrintMessage();
}
}

Hi,

It is typical object oriented technique to work around. But i am not sure.

I though we can't do that. But when your child class have the static method and want to try in differently it may be possible.

I suggest you to work out this.

using mybaseclass = Namespace.BaseClass;

class MyClass : mybaseclass {

static void MyMethod() { mybaseclass.BaseStaticMethod(); }

}

Another way:

public class Parent1
{
public static void Foo()
{
Console.WriteLine("Parent1");
}
}

public class Child : Parent1
{
public new static void Foo()
{
Type parent = typeof(Child).BaseType;
MethodInfo[] methods = parent.GetMethods();
MethodInfo foo = methods.First(m => m.Name == "Foo");
foo.Invoke(null, null);
}
}

hi,

It is not possible.

but you can create simple method instead of static method.
Example:
public class test
{
    public int id { get; set; }
    public string name { get; set; }
    public string GetName()
    {
        return "my name";
    }
}
class test1 : test
{
    public bool IsId { get; set; }
    public string name { get; set; }
    public string MyName()
    {
        return base.GetName();
    }
}
hope this help.
