I have star * delimiter file that finally I need to store in the Array after splitting * delimiter where it is storing value in the array and printing column however it is continuously printing same column value again and again.
Note: There are 60 columns in the txt file.
Following is my code:
static String[] arraylist;
String st;
BufferedReader Br = null;
File objFile = new File("C://DATA//File.txt");
Br = new BufferedReader(new FileReader(objFile));
LineNumberReader lineNumberReader = new LineNumberReader(new FileReader(objFile));
lineNumberReader.skip(Long.MAX_VALUE);
int lines = lineNumberReader.getLineNumber();
System.out.println("Total Rows in the File : " + lines);
List<String> lis = new ArrayList<String>();
while ((st = Br.readLine()) != null) {
arraylist = st.split("\\*");
for (int i = 0; i < arraylist.length; i++) {
lis.add(arraylist[1]);
lis.add("\n");
System.out.println("List value are " +lis);
}
}
Br.close();
Following is column sample: (Similarly there are 60 columns in this file)
*ABC*08*31444*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*66657*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*33161*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*55771*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*20605*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*26471*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*85608*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*57735*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*46844*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*57823*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*31249*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*32394*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*46166*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*46167*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*43108*XYZ*1234*OLNBHJK*^TGJF54DFG908
*ABC*08*43110*XYZ*1234*OLNBHJK*^TGJF54DFG908
I want to print 2nd column only one time: For Example:
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
ABC
All you need to do is to print the second item in the array. Note that the array index start at 0.
while ((st = Br.readLine()) != null) {
arraylist = st.split("\\*");
System.out.println("List value are " + arraylist[1]);
}
