如何将文本文件存储到数组中?

so that later i can parse the array and if the line contains 3 doubles store it into an array of object type? ill later have to store the lines with 3 doubles into another array.

这样以后我就可以解析这个数组如果这个行包含3个双打将它存储到一个对象类型数组中?稍后，我必须将3倍的行存储到另一个数组中。

here's an example of my code so far

下面是我的代码示例。

    public static void readFile(){

    Scanner scnr = null;
    File info = new File("info.txt");
    try {
        scnr = new Scanner(info);
    } catch (FileNotFoundException e) {
        System.out.println("file not found");
        e.printStackTrace();
    }

    int counterLines = 0;
    String nextLine = "";
    while(scnr.hasNextLine()){
        nextLine = scnr.nextLine();
        counterLines ++; 

    }

    System.out.println(counterLines);

    String[] infoArray = new String[counterLines];
    for(int i = 0; i < counterLines; i++){
        infoArray[i] = scnr.nextLine();
        System.out.println(infoArray[i]);

You can probably spilt the text of the file into individual words using String.split() which gives you a String array.

您可以使用String.split()将文件的文本溢出到单个单词中。
