Answer 1

You cannot make class inside class instead of static class.

make Animal class outside Program class

or make Animal class static

public class Program {
static class Animal {
public void makesound(){
System.out.println("AJ");
}

public void makesound(String dog) {
System.out.println (dog);
}

}

public static void main(String[] args) {
Animal abc = new Animal();
abc.makesound();
}
}

Answer 2

Additionallly, I would recommend you to remove the blank spaces:

System.out.println(...)
Instead of
System. out .println (...)

Answer 3

Its a special problem of an inner class.
Define class Animal out of class Program.

Please after writing code check again what you are doing?

You have many mistakes

1 - extends class Animal should be extends Animal
2 - public not publ8c
3 - void not voud

// Created by NonStop CODING
// why it has no output
// Created by subrat yadav

class Animal{
void makesound(){
System.out.println("space");
}

void makesound(String dog){
System.out.println(dog);
}
}

class Cat extends Animal {
public void makesound(){
System.out.println("meau meau");
}
}

public class Program
{
public static void main(String[] args) {

Animal abc= new Animal();
abc.makesound("dog");
Cat xyz=new Cat();
xyz.makesound();
}
}

Answer 6

class Cat extends Animal {
public void makesound(){
System.out.println("meau meau");
}
}

It's "class Cat extends Animal" (line 14)
And it's "public void" (line 15). Check your spellings.

class animal must be static.

Answer 11

you can not call a non-static method / class inside a static method / class.
