void myMethod();       
} 
}        
class NestedInterfaceDemo1 implements MyInterfaceA.MyInterfaceB
{       
public void myMethod(){          System.out.println("Nested interface method");      }              
public static void main(String args[]){            MyInterfaceA.MyInterfaceB obj= new NestedInterfaceDemo1();       obj.myMethod();

Answer 1

Can you write this program in Sololearn Playground and share here?

Answer 2

Kontham Shravani interface declaration is wrong. You have to implement multiple interface with comma not with dot.

No need to create object of interface.

Answer 3

Kontham Shravani When I copied your code in Play Ground and run that then I got error of white space character.

Compare your code with this and see what you did mistake.

----------------
interface MyInterfaceA {
void display();
}

interface MyInterfaceB {
void show();
}

class Demo implements MyInterfaceA, MyInterfaceB {

public void display () {
System.out.println("My interface A");
}

public void show() {
System.out.println("My interface B");
}

public static void main(String[] args) {
Demo d = new Demo();

d.display();
d.show();
}
}

Answer 4

Give me the proper answer in which line I have to remove white space .I can't understand what did you say

Answer 5

Run the program, you can understand that your program has some extra white-space characters. Remove those, then it works.

Edit:
Kontham Shravani
Sry for late response.. Is it resolved?
Nested interface?

There Whice space means :
Complier shows you error at line number: illegal charecter like \u00a0. Go to that line number and remove extra spaces which are there....
