public BufferedInputStream(InputStream in, int size) 

Source Link

Document

Creates a BufferedInputStream with the specified buffer size, and saves its argument, the input stream in, for later use.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {

    InputStream is = new FileInputStream("C:/test.txt");

    // input stream is converted to buffered input stream
    BufferedInputStream bis = new BufferedInputStream(is, 200);
