Java I/O - 如何在读取文件时跳过n个字节

import java.io.File;
import java.io.FileInputStream;

public class Main {

  public static void main(String[] args) throws Exception {
    File file = new File("C:/String.txt");
    FileInputStream fin = new FileInputStream(file);

    int ch;
    // skip first 10 bytes
    fin.skip(10);
    while ((ch = fin.read()) != -1){
      System.out.print((char) ch);
    }
  }
}
