Java Tutorial : Java method overriding(Static method)
Bank.java
public class Bank
{
    public static int getRateOfInterest()
    {
        return 5;
    }
}
Hdfc.java
public class Hdfc extends Bank
{

    /*
     * static method cannot be overridden, because static method is bound with
     * class whereas instance method is bound with object. Static belongs to
     * class area and instance belongs to heap area.
     */
    public static int getRateOfInterest()
    {
        return 10;
    }
}
Icici.java
public class Icici extends Bank
{

    /*
     * static method cannot be overridden, because static method is bound with
     * class whereas instance method is bound with object. Static belongs to
     * class area and instance belongs to heap area.
     */
    public static int getRateOfInterest()
    {
        return 8;
    }
}
MethodOverrideTest.java
public class MethodOverrideTest
{

    public static void main(String[] args)
    {
        Bank bankRef = new Hdfc();
        int rateOfInterest = bankRef.getRateOfInterest();
        
        System.out.println("Rate of Interest provided by HDFC : " + rateOfInterest);

        bankRef = new Icici();
        rateOfInterest = bankRef.getRateOfInterest();
        
        System.out.println("Rate of Interest provided by ICICI : " + rateOfInterest);
    }

}
Output
Rate of Interest provided by HDFC : 5
Rate of Interest provided by ICICI : 5
