Java 似乎无缘无故地调用NoTouchElement异常

我正在尝试制作一个程序来读取数据文件，有点像这样：

01 1 2 3 4 5
02 1 2 3 4 5
03 1 2 3 4 5

等等，到目前为止，我有以下代码：

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

public class fileReader {
    int lineSpaceCount; // number of spaces per line in the input
    int outputSpaceCount; // number of spaces the output will use
    int[] includeData; // data value places that will be included into the output
    String returnText; // text that will be returned

    // CONSTRUCTORS
    public fileReader() {
        this.lineSpaceCount = 0;
        this.outputSpaceCount = 0;

        this.includeData = new int[outputSpaceCount];
    } // default constructor that sets everything to default values

    public fileReader(final int lineSpaceCount, final int outputSpaceCount) {
        this.lineSpaceCount = lineSpaceCount;
        this.outputSpaceCount = outputSpaceCount;

        this.includeData = new int[outputSpaceCount];
    } // constructor to set everything to custom values

    // SETTER METHODS
    public void setIncludeData(final int[] inputArray) {
        for (int i = 0; i < this.includeData.length; i++) {
            this.includeData[i] = inputArray[i];
        }
    }

    public void setOutputSpaceCount(final int outputSpaceCount) {
        this.outputSpaceCount = outputSpaceCount;
    }

    public void setLineSpaceCount(final int lineSpaceCount) {
        this.lineSpaceCount = lineSpaceCount;
    }

    // GETTER METHODS
    public int getLineSpaceCount() {
        return this.lineSpaceCount;
    }

    public int getOutputSpaceCount() {
        return this.outputSpaceCount;
    }

    public int[] getIncludeData() {
        return this.includeData;
    }

    // CUSTOM METHODS
    public String splitFile(final File file) throws IOException {
        int fileLength = 0;
        
        try (
            Scanner counter = new Scanner(new FileReader(file))
            ) {
            while (counter.hasNextLine()) {
                counter.nextLine();
                fileLength++;
                } //counts number of lines in the file
            } //automatically closes the scanner

        final String[] inArray = new String[fileLength]; // array that will contain every line in the file
        String[] secArray = new String[this.lineSpaceCount]; // array that will contain every part of the line for inArray

        try (
            final Scanner input = new Scanner(file);
            ) {
            for (int i = 0; i > -1; i++) {
                inArray[i] = input.nextLine(); //this is where the NoSuchElementException happens

                if (i > fileLength) {
                    i = -1;
                } //if there are no more lines, end loop
            } //puts all the lines of the file into a massive array
        } //automatically closes the scanner

        final String[][] outArray = new String[inArray.length][this.outputSpaceCount]; // output array that will betranslated into text, has to be placed here for the .length attribute of inArray to be correct

        for (int h = 0; h < fileLength; h++) {
            secArray = inArray[h].split(" "); //splits the line into portions

            for (int k = 0; k < secArray.length; k++) {
                outArray[h][k] = secArray[k]; // h = rows, k = columns
            }
        } // nested loops to transfer information into the 2D array

        toText(outArray, fileLength);
        return this.returnText;
    } // massive method that splits a file into individual parts

    public void toText(final String[][] array, final int arrayLength) {
        for (int i = 0; i < arrayLength; i++) {
            for (int j = 0; j < includeData.length; j++ ) {
                this.returnText += array[i] [includeData[j]] + " ";
                } 
            this.returnText += "\n";
            } //method turns the 2D array into a neat output
            //if includeData = {0, 2} and outArray = {{0, 2, 3}{8, 9, 14}} then returnText will equal to 0 3 \n 8 14
        } //method that converts the 2D array into readable text
    }

这里是PovertyData.txt的摘录（超过10000行）

但是，在第75行，

inArray[i]=input.nextLine（），出现NoTouchElement异常并显示此错误消息：

Exception in thread "main" java.util.NoSuchElementException: No line found
        at java.base/java.util.Scanner.nextLine(Scanner.java:1651)
        at fileReader.splitFile(fileReader.java:75)
        at Main.main(Main.java:15)

PovertyData.txt的第1651行如下：

我不知道为什么会发生这种情况，因为“文件”中有数据，Station所做的就是将文件的每一行读取到一个数组中。请告诉我为什么会发生这种情况或如何解决它

谢谢。
在读取文件时，for循环中有一个bug。
在Java中，有一种更简单的方法来读取文件中的所有行，而不是修复它

List<String> allLines = Files.readAllLines(file.toPath());
String[] inArray = new String[allLines.size()];
allLines.toArray(inArray); 

List allLines=Files.readAllLines（file.toPath（））；
String[]inArray=新字符串[allLines.size（）]；
所有行。toArray（inArray）；
for（int i=0；i>-1；i++）对这种循环条件有什么期望{

？尝试

i

而不是

i>-1

。我看到的一个问题是，您对同一数据使用多个扫描仪。问题是，如果关闭一个扫描仪，文件也会关闭。@nomaker我该如何解决这个问题？只需对每个文件使用一个扫描仪，并且在程序结束之前不要关闭它。@hev1谢谢，th在suggestion+magikarp的回答中修复了它：）您找到错误了吗？是的，因为循环条件无效，而不是

i>-1

，它应该是

i

，就像@hev1注释的那样。

List<String> allLines = Files.readAllLines(file.toPath());
String[] inArray = new String[allLines.size()];
allLines.toArray(inArray);
