Java - 从文本文件创建字符串数组

Question

这个问题已经有答案了:

Java: Reading a file into an array (5 个回答)

已关闭 1 年前。

我有一个像这样的文本文件:

abc def jhi
klm nop qrs
tuv wxy zzz

我想要一个像这样的字符串数组:

String[] arr = {"abc def jhi","klm nop qrs","tuv wxy zzz"}

我已经尝试过:

try
    {
        FileInputStream fstream_school = new FileInputStream("text1.txt");
        DataInputStream data_input = new DataInputStream(fstream_school);
        BufferedReader buffer = new BufferedReader(new InputStreamReader(data_input));
        String str_line;
        while ((str_line = buffer.readLine()) != null)
        {
            str_line = str_line.trim();
            if ((str_line.length()!=0)) 
            {
                String[] itemsSchool = str_line.split("\t");
            }
        }
    }
catch (Exception e)  
    {
     // Catch exception if any
        System.err.println("Error: " + e.getMessage());
    }

请大家帮帮我......所有答案将不胜感激...

如果您使用 Java 7，由于the Files#readAllLines method，它可以在两行内完成。 :

List<String> lines = Files.readAllLines(yourFile, charset);
String[] arr = lines.toArray(new String[lines.size()]);
