Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    byte[] bytes = new byte[] { 0x1, 0x00, 0x00 };
    BigInteger bi = new BigInteger(bytes);
    bi = bi.or(bi);
}

From source file:Main.java

public static void main(String[] args) {

    // assign values to bi1, bi2
    BigInteger bi1 = new BigInteger("6");
    BigInteger bi2 = new BigInteger("8");

    // perform or operation on bi1, bi2
    BigInteger bi3 = bi1.or(bi2);

    System.out.println(bi3);//from w  ww. ja  v  a 2s .co m
