Post the correct code you have permission to take change only in public class.....

class a
{
a()
{
System.out.println("mohit kumar singh a");
}
}
class b extends a
{
b()
{
System.out.println("mohit kumar singh b");
}
}
class c extends b
{
int x;
c()
{
x=y;
System.out.println("mohit kumar singh c");
System.out.println("x= "+x);
}
}
public class f extends c
{
public static void main(String args[])
{
c t=new c();
}
}

class a
{
int y;//here we have declare y.
a()
{
System.out.println("mohit kumar singh a");
}
}
class b extends a
{
b()
{
System.out.println("mohit kumar singh b");
}
}
class c extends b
{
int x;//you do not the permission to eliminate this
c()
{
x=y;//you do not the permission to eliminate this
System.out.println("mohit kumar singh c");
System.out.println("x= "+x);//you do not have permission to eliminate this.
}
}
public class f
{
public static void main(String args[])
{
c t=new c();
}
}
Mohit am i right.
Just we have to initialize y inside class a.

Please always wrap your code inside
```
... [ /code]  tags.
```

Hello Mohit
as far as i know that you only created the object for the class c but didn't use it.so it might be the error.and what sushant told is also right that we should also declare y veriable inside the class A

since c has a constructor: c(int y) you must satisfy that constructor when you extend it. In other words r extends c but c has a constructor that requires an integer therefore r must satisfy this. You could add c() {} in class c to allow for an empty constructor or a better solution is to use super to set the constructor to a default value such as zero when constructing r: r() { super(0); } or if you wanted r(int y) { super(y); } See the Example:

class a
{
a()
{
System.out.println("mohit kumar singh a");
}
}
class b extends a
{
b()
{
System.out.println("mohit kumar singh b");
}
}
class c extends b
{
int x;
c(int y)
{
x=y;
System.out.println("mohit kumar singh c");
System.out.println("x= "+x);
}
}
class r extends c
{
r() { super(0); }
public static void main(String args[])
{
c t=new c(4);
}
}

Oh!! sorry guy's actually i missed int y in constructor.
Well i try to avoid this type of mistakes in my next java programming challenge.
So wait for my next challenge.
