Unreported exception java.lang.Exception; must be caught or declared to be thrown [duplicate]

by

public static byte[] m16h(byte[] m) throws Exception

The signature of your method indicates that an Exception is susceptible of being thrown.

This means that the exception either :

  1. Must be handled by the caller

    try {
    System.out.println(xor(m16h(add(xor(xor(m16h(add(k1, m16h(add(k2, m16h(k3))))), k3), k2), k1)), k3));
} catch (Exception e) {
    e.printStackTrace();
}

  2. Must be rethrowed by the caller

    public static void main(String[] args) throws Exception
