Doubt in inner class

[Debashree Halder]

package practiceSCJP;
 
class MyOuter{
 
public class MyInner{
public void doStuff(){
System.out.println("doStuff");
}
 
}
class MyInner2 extends MyInner{
public void doStuff(){
System.out.println("doStuff overridden");
}
public void dostuff(String s){
System.out.println("doStuff overloaded" +s);
}
}
}
 
public class InnerExamples {
 
public static void main(String[] args) {
MyOuter.MyInner mi1 = new MyOuter().new MyInner();
MyOuter.MyInner2 mi2 = new MyOuter().new MyInner2();
mi1.doStuff();
mi2.doStuff();
mi2.doStuff("pop");
MyOuter.MyInner mi3 = new MyOuter().new MyInner2();
mi3.doStuff();
}
 
}

If I attempt to run this code it says
"Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method doStuff() in the type MyOuter.MyInner2 is not applicable for the arguments (String)

at practiceSCJP.InnerExamples.main(InnerExamples.java:30)"

Please explain...

 public static void main(String[] args) {
MyOuter.MyInner mi1 = new MyOuter().new MyInner();
MyOuter.MyInner2 mi2 = new MyOuter().new MyInner2();
mi1.doStuff();
mi2.doStuff();
[B]mi2.doStuff("pop"); // there in no method doStuff(String) in MyInner2...its dostuff(String)[/B]
MyOuter.MyInner mi3 = new MyOuter().new MyInner2();
mi3.doStuff();
}   

Hi,

Is that a typo? Change the mi2.doStuff("pop") to mi2.dostuff("pop")
It compiles and runs properly!

Hope this helps!
