1)class CloneTest
{

public static void main(String args[])
{
int ia[][] = {{1,2},null};
int ja[][] =(int[][])ia.clone();
System.out.println((ia==ja) + "");
System.out.println(ia[0] == ja[0] && ia[1] == ja[1]);
}
}
this method should throw CloneNotSuportedException beacause it is a checked exception
2)can anyone give me some examples where the compiler will give the error the code is unreacheable.

For the answer to 2)
public class Test(){
public int aMethod() throws Exception
{
int x=0;
throw Exception();
return x; // this will be unreachable
}
}

Hi,shabbir ZaKir
since all the arrays are considered to implement cloneable interface there will no exception.check with clone() in API.
