How to merge two sorted arrays into a sorted array? [closed]

Answer 1

Maybe use System.arraycopy

public static byte[] merge(byte[] first, byte[] second){
    int len = first.length + second.length;
    byte[] full = new byte[len];
    System.arraycopy(first, 0, full, 0, first.length);
    System.arraycopy(second, 0, full, first.length, second.length);
    return full;
}
