Which of the following is true about the use of modifiers?
(a)
If no accessibility modifier (public, protected, and private) is specified for a member declaration, the member is only accessible for classes in the package of its class and subclasses of its class anywhere
(b)
You cannot specify accessibility of local variables. They are only accessible within the block in which they are declared
(c)
Subclasses of a class must reside in the same package as the class they extend
(d)
Local variables can be declared static
(e)
None of the above.

public class Program
{
public static void main(String[] args) {
try{
int[] a={1,2,3,4};
for(int i=1;i<=4;i++){
System.out.println("a["+i+"]="+a[i]+"\n");
}
}
catch(Exception e){
System.out.println("error="+e);
}
catch(ArrayIndexOutOfBoundsException e){
System.out.println("ArrayIndexOutOfBoundsException");
}
}
}
A)Compile Time Error
B) Runtime Error
C) Error Code is printed
D) Array is printed

What will be the output of the following code -
import java.util.Map;
import java.util.TreeMap;
public class TreeMapTest
{
public static void main(String[] args) {
Map<Integer,String> m=new TreeMap<Integer,String>();
m.put(11,"audi");
m.put(null,null);
m.put(11,"bmw");
m.put(null,"fer");
System.out.println(m.size());
System.out.println(m);
}
}
