Creates ByteArrayInputStream that uses buf as its buffer array.

Usage

From source file:Main.java

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

    byte[] buf = { 65, 66, 67, 68, 69, 70, 71, 72, 73 };

    // create new byte array input stream
    ByteArrayInputStream bais = new ByteArrayInputStream(buf, 2, 3);

}

From source file:Main.java

public static byte[] decompressInGzip(byte[] compressData, int offset, int length) throws Exception {

    ByteArrayInputStream bis = new ByteArrayInputStream(compressData, offset, length);

    ByteArrayOutputStream bos = new ByteArrayOutputStream();

    int count;/*  w w  w .  j a va 2s.c om*/
    byte[] buf = new byte[1024];
    while ((count = gzipInStream.read(buf)) > 0) {

    }
    gzipInStream.close();

    byte[] originalData = bos.toByteArray();
    bos.close();
