java需要数组列表的指导

Question

我该如何让我的txt输出以下格式！它只输出我输入的第一行，但希望它如下所示>&燃气轮机

这是一个我希望输出看起来如何的示例-http://i.stack.imgur.com/7Lfr0.png

变量“gamerReport”是为第一行设置的，除了打印它之外，再也不会碰它，列表“al”中添加了内容，但从未使用过。也许试试这样的

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Scanner;
import java.util.ArrayList;
import java.util.List;



public class GAMESCORE {

private static char[] input;

public static void main(String[] args) {

    int totalGames, totalAchievements, totalTime;

    totalGames = 0;
    totalAchievements = 0;
    totalTime = 0;

    String gamerName, gamerReport;

    @SuppressWarnings("resource")
    Scanner Scan = new Scanner(System.in);


    System.out.println("        Game Score Report Generator        ");
    System.out.println("     ");


    System.out.println("Enter Your Name");
    gamerName = Scan.nextLine();
    boolean isEmpty = gamerName == null || gamerName.trim().length() == 0;

    if (isEmpty) {

        System.out.print("Enter your Name.");

        gamerName = Scan.nextLine();
    }



    System.out.println("Enter details in this format - " + "  >");
    System.out.println("    ");



    System.out.println("Game : Achievement Score : Minutes Played");
    gamerReport = Scan.nextLine();
    Scanner scanner = new Scanner(System.in);

    List<String> al = new ArrayList<String>();
    String word;

        }

        writer.println();
