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
线程“main”中的异常java.lang.ArrayIndexOutOfBoundsException:1 在Jclass.main(Jclass.java:18)
答案 0 :(得分:2)
因为只有4个制表符分隔值
试
System.out.println(values[0]+"-"+values[1]+"\t"+values[2]+"\t"+values[3]);
就个人而言,我会把它放在循环中
for (String val : values) {
System.out.print (val + "\t");
}
System.out.println ();
