@Ramchandra We can not overide toString() method but we can overide normal method on it ..
for example -
package com.app.test.tt;

import

@FunctionalInterface
interface I13 {

public default String tj() {
return "M1";
}

void sum();

default int add() {

System.out.println("add method in interface
return 0;
}

}

@FunctionalInterface
interface I1 extends I13 {

void sum();

@Override
default String tj() {
return I13.super.tj();
}

@Override
default int add() {
int count = 0;
// I13.super.add();
count++;
System.out.println("add method in interface + count);
return count;
}

}

public class TestJava implements I1 {
public static void main(String[] args) {

I1 obj = new TestJava();

obj.add();

}// end

@Override
public String tj() {
// TODO Auto-generated method stub
return I1.super.tj();
}

@Override
public void sum() {
}

@Override
public int add() {

System.out.println("in override in impl class..");
return I1.super.add();
}

}
