java - 将文件内容拆分到 ArrayList 中

Question

我有一个文件，我可以在其中读取其内容。现在我想将每个单独的行单独拆分为一个 arrayList 但无法成功。

这就是我目前所拥有的

try {
        input = new FileInputStream(test);


        byte testContent[] = new byte[(int) test.length()];
        input.read(testContent);


        String testFile = new String(testContent);
        System.out.println(testFile);

    }

文件内容示例如下，

0,0,5,13,​​9,1,0,0,0,0,13,15,10,15,5,0,0,3,15,2,0,11, 8,0,0,4,12,0,0,8,8,0,0,5,8,0 0,0,0,12,13,5,0,0,0,0,0,11,16,9,0,0,0,0,3,15,16,6,0,0,0, 7,15,16,16,2,0,0,0,0,1,1 0,0,0,4,15,12,0,0,0,0,3,16,15,14,0,0,0,0,8,13,8,16,0,0,0, 0,1,6,15,11,0,0,0,1,8,1 0,0,7,15,13,​​1,0,0,0,8,13,6,15,4,0,0,0,2,1,13,13,0,0,0,0, 0,2,15,11,1,0,0,0,0,0,1 0,0,0,1,11,0,0,0,0,0,0,7,8,0,0,0,0,0,1,13,6,2,2,0,0, 0,7,15,0,9,8,0,0,5,16,10,0,1

我希望上面的内容像这样的数组

[0,0,5,13,​​9,1,0,0,0,0,13,15,10,15,5,0,0,3,15,2,0,11 ,8,0,0,4,12,0,0,8,8,0,0,5,8,0] [0,0,0,12,13,5,0,0,0,0,0,11,16,9,0,0,0,0,3,15,16,6,0, 0,0,7,15,16,16,2,0,0,0,0,1,1] [0,0,0,4,15,12,0,0,0,0,3,16,15,14,0,0,0,0,8,13,8,16,0, 0,0,0,1,6,15,11,0,0,0,1,8,1] [0,0,7,15,13,​​1,0,0,0,8,13,6,15,4,0,0,0,2,1,13,13,0,0, 0,0,0,2,15,11,1,0,0,0,0,0,1] [0,0,0,1,11,0,0,0,0,0,0,7,8,0,0,0,0,0,1,13,6,2,2, 0,0,0,7,15,0,9,8,0,0,5,16,10,0,1]

预先感谢您的帮助

怎么样Files.readAllLines() :

List<String> lines = Files.readAllLines(new File(test).toPath());

如果您使用的是 Java 7，则需要此版本:

List<String> lines = Files.readAllLines(new File(test).toPath(), StandardCharsets.UTF_8);
