This document discusses how to achieve multiple inheritance in Java using interfaces. It defines two interfaces, Father and Mother, that each contain a float variable and method to get height. A Child class implements both interfaces and overrides the height method to calculate and print the average height from the interfaces. The code is tested in a main method that creates a Child object and calls its height method.

1. //Ques. 15 How to achieve multiple inheritance by using interface in java?
interface Father
{
float HT = 6.2f;
void height();
}
interface Mother
{
float HT = 5.8f;
void height();
}
class child implements Father, Mother
{
public void height()
{
float HT = (Father.HT + Mother.HT)/2;
System.out.println("n child's height = "+HT);
}
}
class Multi
{
public static void main(String args[])
{
childch = new child();
ch.height();
