Traversing through a stack of objects, and puttin them info in an array

[szimme101]

What is a good way to go through a stack of objects?

I have to compare each object of the stack, to a object I have predifined and then put that object into an array. Stopping this "process" when I find a match.

Assuming there will be a match and that the stack is not empty what would you recommend I do?


Thanks,

Check the Stack class api in the javadocs to learn what methods are available.

Code:

import java.util.*;

public class StackTest {
    public static void main(String[] args) {
        String[] names = {
            "Alice", "Sam", "John", "Mary", "Nancy", "Fred"
        };
        String searchFor = "John";
        Stack<String> stack = new Stack<String>();
        for(int i = 0; i < names.length; i++)
            stack.push(names[i]);
        System.out.println("stack = " + stack);
        // Look for searchFor string in stack:
        String[] stackItems = new String[stack.size()];
        int size = stack.size();
        for(int i = 0; i < size; i++) {
            String s = stack.pop();
            if(s.equals(searchFor)) {
                System.out.println("Found " + searchFor +
                                   " at index of " + i + " in stack.");
                break;
            }
            stackItems[i] = s;
        }
        System.out.println(Arrays.toString(stackItems));
    }
}
