Skips over and discards n bytes of data from the input stream.

Usage

From source file:Main.java

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

    int ch;/* w w w .j  a va 2  s. c o  m*/
    // skip first 10 bytes
    fin.skip(10);
    while ((ch = fin.read()) != -1) {
        System.out.print((char) ch);
    }
}
