MyInteger(int i){
this.i=i;
}
int intValue(){

}

public String toString() {
return String.valueOf(i);
}

}
/*class MyInteger1 extends Integer {
//error because Integer is a final class
}*/
public class MyIntegerDemo {
public static void main(String[] nt) {
MyInteger mi=new MyInteger(10);
int j = mi.intValue();
System.out.println(mi);
System.out.println(j);
}
}
