Why the program is showing errors
interface MyInterfaceA { void display(); interface MyInterfaceB { 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(); } }

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

Kontham Shravani interface declaration is wrong. You have to implement multiple interface with comma not with dot.
No need to create object of interface.

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();
}
}

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

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....
