Question

try (BufferedReader br = new BufferedReader(new FileReader("/home/modi/Desktop/hbaseoff/mobiledata.txt")))
        {

            String sCurrentLine;

            while ((sCurrentLine = br.readLine()) != null) {
                String[] values = sCurrentLine.split("\t");
System.out.println(values[0]+"-"+values[1]+"\t"+values[2]+"\t"+values[3]+"\t"+values[4]);
}

        } catch (IOException e) {
            e.printStackTrace();
        } 

输出:

20150320-9876543217 16  45  22
20150320-8876543218 45  11  13
20150320-8876543219 49  15  16
20150321-9876543210 16  45  22
20150321-9876543211 45  11  13

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1 at Jclass.main(Jclass.java:18)

Answer 1

因为只有 4 个制表符分隔值

尝试

System.out.println(values[0]+"-"+values[1]+"\t"+values[2]+"\t"+values[3]);

我个人会把它放在一个循环中

for (String val : values) {
   System.out.print (val + "\t");
}
System.out.println ();
