Question

While adding the lines of a text file to List , i donot want to add empty lines to the List. I tried this but not working :

Scanner s=new Scanner(new File(text.txt));
List <String> names=new ArrayList<String>();
while(s.hasNext()){
if (s.nextLine()!=null){
names.add(s.nextLine());
}}

My text file looks like this:

name1   erer    | 26-08-1988

name2 rerer   | 13-07-1988       

name3  erer    | 14-07-1988   

name4  weww |   13-07-2001   
name5 ewew | 18-10-1987   

Answer 1

You skip a line each time (double call to nextLine() in each iteration), should be:

String line;
if ((line=s.nextLine())!=null && !line.trim().equals("")){
    names.add(line);
}

or even:

if (!"".equals(line=s.nextLine()))
