Reading A File Into A List - With JDK 1.7 …And Without Streams


import java.io.IOException;
import static java.nio.charset.Charset.*;
import static java.nio.file.Files.*;
import static java.nio.file.Paths.*;
import java.util.List;


public class FileReader {

    public static void read(String file) throws IOException{
        List<String> allLines = readAllLines(get(file), defaultCharset());
        for (String line : allLines) {
            System.out.println(line);
        }
    }

    public static void main(String[] args) throws IOException {
        read("./readme.txt");
    }
}

And this works only in JDK7? Why isn´t this possible in jdk6?

oh those static imports.... do not make this code readable, in my opinion

I do not like these static wildcard imports...which method belongs to which class?

I think the list should be like this??
List <String> allLines = readAllLines(get(file), defaultCharset());

How is this not a C like example?

Where's the implementation of readAllLines?

So when an 'Autocloseable' gets out of scope it gets closed?

how about for example jdbc-Connections from a Pool? looks error-prone to me...

@Gurnah,

you are right: it is List<String> -> I forgot to escape the generic brackets and it was swallowed by the browser,

thanks for the reminder!,
