我想从一行中提取字符串

Question

以下内容在文本文件中可用。我想提取数据（姓名，年龄，工作经验，职位）。我能怎么做？我尝试使用java stringtokenizer和split函数提取数据。但是无法提取数据。

Name                                     Age                   Working Experience          Position                     
John                                     23                    10                          Team Leader                          
Christian Elverdam                       27                    7                           Director                    
Niels Bye Nielsen                        59                    16                          Composer
Rajkumar Hirani                          40                    23                          Director               
Vidhu Vinod Chopra                      58                    21                          Screenplay

预期产量：

John              |23|10|Team Leader|
Christian Elverdam|27|7 |Director   |
Niels Bye Nielsen |59|16|Composer   |
Rajkumar Hirani   |40|23|Director   |
Vidhu Vinod Chopra|58|21|Screenplay |

Answer 1

请勿使用StringTokenizer：

  

StringTokenizer是一个遗留类，出于兼容性原因保留，尽管在新代码中不鼓励使用它。建议寻求该功能的任何人都使用split的{​​{1}}方法或String软件包。

如果您在两个或多个空格上分开，可以使用split()：java.util.regex

演示

split(" {2,}")

输出

String input = "Name                                     Age                   Working Experience          Position                     \n" +

               "Rajkumar Hirani                          40                    23                          Director               \n" +
               "Vidhu Vinod Chopra                      58                    21                          Screenplay\n";

List<String[]> rows = new ArrayList<>();
try (BufferedReader in = new BufferedReader(new StringReader(input))) {
    in.readLine(); // skip header line
    for (String line; (line = in.readLine()) != null; ) {
        rows.add(line.split(" {2,}"));
    }
}
for (String[] row : rows)
    System.out.println(Arrays.toString(row));
