java - 如何从数组中删除一个值

Question

我想从文本文件中获取的数组中删除第三个值。我的文本文件如下所示:

item = 0    Dwarf_remains   The_body_of_a_Dwarf_savaged_by_Goblins. 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0
item = 1    Toolkit Good_for_repairing_a_broken_cannon. 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0
item = 2    Cannonball  Ammo_for_the_Dwarf_Cannon.  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0
item = 3    Nulodion's_notes    It's_a_Nulodion's_notes.    0   0   0   0   0   0   0   0   0   0   0   0   0   0   0
item = 4    Ammo_mould  Used_to_make_cannon_ammunition. 0   0   0   0   0   0   0   0   0   0   0   0   0   0   0
item = 5    Instruction_manual  An_old_note_book.   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0

然后我想删除所有这些东西:

The_body_of_a_Dwarf_savaged_by_Goblins.
Ammo_for_the_Dwarf_Cannon.
It's_a_Nulodion's_notes.
Used_to_make_cannon_ammunition.
An_old_note_book.

我现在正在使用这段代码来获取数组

import java.io.*;

public class Main {
    public static void main(String [] args) {

        // The name of the file to open.
        String fileName = "Items.cfg";

        // This will reference one line at a time
        String line = null;

        try {
            // FileReader reads text files in the default encoding.
            FileReader fileReader = 
                new FileReader(fileName);

            // Always wrap FileReader in BufferedReader.
            BufferedReader bufferedReader = 
                new BufferedReader(fileReader);

            while((line = bufferedReader.readLine()) != null) {
                String[] values = line.split("\\t");
                System.out.println(values[2]);
            }    

            // Always close files.
            bufferedReader.close();            
        }
        catch(FileNotFoundException ex) {
            System.out.println("Unable to open file '" + fileName + "'");                
        }
        catch(IOException ex) {
            System.out.println("Error reading file '"  + fileName + "'");                   
            // Or we could just do this: 
            // ex.printStackTrace();
        }
    }
}

当 java 删除所有这些时，是否可以将更新的文件保存在另一个文件中，例如 Items2.cfg 或其他文件？

例如这里类似于此？我复制了答案以便于访问。 Removing an element from an Array (Java)

array = ArrayUtils.removeElement(数组, 元素)
