如何使LinkedList从另一个类可访问main？

Question

How can I access the linked list to a different class that has the main method?

import java.util.LinkedList;

public class Project {
    public Project {
        // Linked list declaration: 
        LinkedList<Character>list = new LinkedList<Character>();
    }
}

Answer 1

Declare it in the original class (eg Project.java) as:

public static LinkedList<Character> list = new LinkedList<Character>();

Call it from another class as:

LinkedList<Character> ll = Project.list;

If data hiding is of essence to you, then you need to set up getters/setters for it.
