在java中讀取.txt文件時獲取ArrayIndexOutOfBoundsException

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();
        } 

輸出：

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

線程“主”中的異常java.lang.ArrayIndexOutOfBoundsException：Jclass.main處為1（Jclass.java:18）

Answer 1

因為只有4個制表符分隔值

嘗試

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

我個人會把這個循環

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