BufferedReader pour ignorer la première ligne

Je suis en utilisant le suivant bufferedreader de lire les lignes d'un fichier,

BufferedReader reader = new BufferedReader(new FileReader(somepath));
while ((line1 = reader.readLine()) != null) 
{
    //some code
}

Maintenant, je veux sauter la lecture de la première ligne du fichier et je ne veux pas utiliser un compteur de ligne int lineno de garder un nombre de lignes.

Comment faire?

    Vous pouvez essayer ce

     BufferedReader reader = new BufferedReader(new FileReader(somepath));
 reader.readLine(); //this will read the first line
 String line1=null;
 while ((line1 = reader.readLine()) != null){ //loop will run from 2nd line
        //some code
 }

    Utiliser un linenumberreader à la place.

    LineNumberReader reader = new LineNumberReader(new InputStreamReader(file.getInputStream()));
            String line1;
            while ((line1 = reader.readLine()) != null) 
            {
                if(reader.getLineNumber()==1){
                    continue;
                }
                System.out.println(line1);
            }

    File file = new File("path to file");
FileInputStream fis = new FileInputStream(file);
BufferedReader br = new BufferedReader(new InputStreamReader(fis));
String line = null;
int count = 0;
while((line = br.readLine()) != null) { //read through file line by line
    if(count != 0) { //count == 0 means the first line
        System.out.println("That's not the first line");
    }
    count++; //count increments as you read lines
}
br.close(); //do not forget to close the resources

    Vous pouvez créer un compteur qui contient la valeur de la ligne de départ:

    private final static START_LINE = 1;

BufferedReader reader = new BufferedReader(new FileReader(somepath));
int counter=START_LINE;

while ((line1 = reader.readLine()) != null) {
  if(counter>START_LINE){
     //your code here
  }
  counter++;
}
