BufferedReader跳过第一行

Question

我使用下面的bufferedreader读取文件的行，

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

现在，我想跳过读取文件的第一行，我不想使用计数器行int lineno来记录行数。

这要怎么做？

Answer 1

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

Answer 2

您可以使用Stream kip（）函数，如下所示：

BufferedReader reader = new BufferedReader(new FileReader(somepath));   
Stream<String> lines = reader.lines().skip(1);

lines.forEachOrdered(line -> {

...
});

Answer 3

你可以试试这个

 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
 }
