Question

我有一个Java程序可以解决手机的常见问题。为此，我设置了一个扫描程序，用于读取任何关键字的用户输入。如果找到其中一个关键字，则方法将从文本文件中输出该关键字建议的问题的解决方案。

我的问题是，当我运行程序时，从每个方法输出文本文件中的所有行，忽略我的输入。

以下是代码：

    import java.io.BufferedReader;
    import java.io.FileReader;
    import java.io.IOException;
    import java.util.Scanner;

    public class task2 {

public static void main(String[] args) {

    Scanner scan = new Scanner(System.in);
    System.out.println("What is your problem?");
    String input =  scan.nextLine();
    String[] problems = {"screen", "display", "broken", "cracked", "camera", "flash", "ports"};
    String[] solutions = input.split("broken");

    for(int x=0; x < problems.length; x++){
        if(input.contains("broken")){
            if(input.contains("screen")){
                brokenScreen();
            } else{

            }
            if(input.contains("display")) {
                brokenDisplay();
            } else{

            }
            if(input.contains("camera")) {
                brokenCamera();
            } else{

            }
            if(input.contains("flash")) {
                brokenFlash();
            } else{

            }
            if(input.contains("ports")) {
                brokenPorts();
            } else{

            }
        }
            else{

            }

        if(input.contains("cracked")) {
            if(input.contains("screen")) {
                crackedScreen();
            } else{

            }
        }
        if(input.contains("water")) {
            waterPhone();
        }
        else{
        }
    }

    brokenScreen();
    brokenDisplay();
    crackedScreen();
    brokenCamera();
    brokenFlash();
    brokenPorts();
    waterPhone();
    noSolution();

    }

public static void noSolution() {

    try {
        FileReader filereader = new FileReader(file);
        BufferedReader bufferedreader = new BufferedReader(filereader);
        while((file = bufferedreader.readLine()) != null){
            System.out.println(file);

任何人都可以解决这个问题吗？任何帮助将不胜感激。

删除

brokenScreen();
brokenDisplay();
crackedScreen();
brokenCamera();
brokenFlash();
brokenPorts();
waterPhone();
noSolution();

在main方法的最后（for循环之后）。

程序输出来自多种方法的代码，而不仅仅是一种方法
