LinkedListExamples

[k_o_bliss]

i want this program to print out the message "hello there stranger" but the compiler says i've completed the tool successfully but its saying i have used unchecked or unsafe operations. it says i should recompile with XLint whats this?

import java.util.*;

class LinkedListExample
{
public static void main(String args[])
{
LinkedList list = new LinkedList();

list.add(new String("Hello"));
list.add(new String("there"));
list.add(new String("stranger"));

String sentance = "";

for(int i = 0; i < list.size(); i++)
{
sentance += list.get(i) + " ";
}

System.out.println(sentance);

return;
}
}

-Xlint is a compiler option. Run javac with the -Xlint option.

Looks like in your code, the list.add(new String("Hello")); is the part thats causing the unchecked warning coz you r using a raw type i.e new LinkedList() and the compiler does not know/does not have enuf info to check if your LinkedList can accept strings.
