I want every line in my textdoc to be assigned to a variable.
import java.io.*;
import static java.lang.System.*;
class readfile {
public static void main(String[] args) {
try {
FileReader fr = new FileReader("filename");
BufferedReader br = new Buffered(fr);
String str;
while ((str = br.readLine()) != null) {}
br.close();
} catch (IOException e) {
out.println("file not found");
}
}
}
I would suggest you create a List and store every line in a list like below:
String str;
List<String> fileText = ....;
while ((str = br.readLine()) != null) {
fileText.add(str);
}
A Java 8 solution for creating a List of lines
Path path = Paths.get("filename");
List<String> lines = Files.lines(path).collect(Collectors.toList());
why do you want to add each line to a separate variable? It is better to add the lines to a list. Then you can access any line as you want.
In JDK 6 or below
List<String> lines = new ArrayList<String>();
while(reader.ready())
lines.add(reader.readLine());
In JDK 7 or above
List<String> lines = Files.readAllLines(Paths.get(fileName),
Charset.defaultCharset());
I would do
List<string> allText= new List<String>();
While(str.hasNextLine){
allText.add(str.nextLine);
}
