Question

In JAVA the method getByte() is undefined for for Ints, Booleans and all primitive data types (I believe).

• Is there a way I can get my Boolean and/or Int variables to work with
  the method.
• Or what data type do you recommend i change the variables too.

Answer 1

You can use ByteBuffer to convert primitives to byte[] and vice versa

Example

public static byte[] toByteArray(int value) {
    ByteBuffer bb = ByteBuffer.allocate(4).order(ByteOrder.nativeOrder());
    return bb.putInt(value).array();
}

public static int toInteger(byte[] bytes) {
    ByteBuffer bb = ByteBuffer.wrap(bytes).order(ByteOrder.nativeOrder());
    return bb.getInt();
}
