we cannot override a static method but we can overload a 
static method.
Ex: override is not possible
class Foo {
    public static void classMethod() {
        System.out.println("classMethod() in Foo");
		
    }

    public void instanceMethod() {
        System.out.println("instanceMethod() in Foo");
    }
}

class Bar extends Foo {
    public static void classMethod() {
        System.out.println("classMethod() in Bar");
		
    }

    public void instanceMethod() {
        System.out.println("instanceMethod() in Bar");
    }
}
 
class StaticHiding {
    public static void main(String[] args) {
        Foo f = new Bar();
		
        f.instanceMethod();
        f.classMethod();


when u run this program output will be:
          instanceMethod() in Bar
          classMethod() in Foo.

Ex: overload is possible
public class abc
{
	public static void main(String args[])
	{

	}
	public static void trss()
	{

	}
	public static void trss(int i)
	{
	}

}
