Append Big-Endian or Little-Endian Integers

Demonstrates how to append integers in big-endian or little-endian byte order to a BinData.

Note: This example requires Chilkat v9.5.0.77 or greater.

import com.chilkatsoft.chilkat2.BinData;

public class ChilkatExample {

    public static void main(String[] args) {
        BinData bd = new BinData();

        // The hex value of decimal 123456789 is 0x075BCD15
        int x = 123456789;

        // Appending little-endian causes bytes to be
        // appended in the order 0x15, 0xCD, 0x5B, 0x07
        boolean littleEndian = true;
        bd.appendInt4(x, littleEndian);

        System.out.println(bd.getEncoded("hex"));
        // Output is: 15CD5B07

        // Now append the same integer in big-endian byte order.
        // Appending bit-endian causes bytes to be
        // appended in the order 0x07, 0x5B, 0xCD, 0x15
        littleEndian = false;
        bd.appendInt4(x, littleEndian);

        System.out.println(bd.getEncoded("hex"));
        // bd now contains: 15CD5B07075BCD15

        // -------------------------------------------
        // Now do the same thing with 16-bit integers
        bd.clear();

        // 1234 decimal = 0x04D2 hex.
        x = 1234;

        littleEndian = true;
        bd.appendInt2(x, littleEndian);

        System.out.println(bd.getEncoded("hex"));
        // Output is: D204
