Returns the number of remaining bytes that can be read (or skipped over) from this input stream.

Usage

From source file:Main.java

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

    byte[] buf = { 65, 66, 67, 68, 69 };

    ByteArrayInputStream bais = new ByteArrayInputStream(buf);

    bais.close();//from ww  w. jav a  2  s .co m

    int count = bais.available();
}

From source file:Main.java

public static void main(String[] arg) throws Throwable {

    int bytesRead = 0;

    ByteArrayOutputStream bao = new ByteArrayOutputStream();

    while ((bytesRead = in.read(buff)) != -1) {
        bao.write(buff, 0, bytesRead);/* ww  w  .j a v  a 2s .c  om*/
    }
    in.close();

    byte[] data = bao.toByteArray();

    ByteArrayInputStream bin = new ByteArrayInputStream(data);
