Blast From The Past: February 21, 2024 - My Only Request

Nothing to think about, nothing to display. This day and every day goes away. The way of the dinosuars they don’t stick around. Everything and everyone ends up on the ground. It is but a moment in this life it would seem, no one wants to be in that gleam. So toss away your thoughts, your considerations at best, make life peaceful that is my only request.

Command line Arguments in Java

I found the code I was looking for:

static class Args {

    public static Map<String, List<String>> parseArgs(String[] args, Set<String> validArgs) {
        Map<String, List<String>> map = new HashMap<>();

        List<String> options = null;

        for (String a : args) {
            if (a.charAt(0) == '-') {
                if (a.length() < 2) {
                    throw new IllegalArgumentException("Invalid Argument: " + a);
                }
                if (!validArgs.contains(a)) {
                    throw new IllegalArgumentException("Invalid Argument: " + a);
                }
                options = new ArrayList<>();
                map.put(a, options);
            } else if (options != null) {
                options.add(a);
            } else {
                throw new IllegalArgumentException("Invalid Argument: " + a);
            }
        }
        return map;
    }
}

I've modified this piece of code then was in the original post. You can pass this a Set of Strings that ensure only the correct proper argumetns are being passed into the program as to not waste the programs time trying to decide if they are proper later.

Didn't Sleep

 What's the point of sleep anymore if I can't sleep? I don't think I slept any good last night. I was awake at 3 am wondering to myself, what on earth am I doing awake? Yeah, that happened. It doesn't make any sense. Fortunately, it's the weekend. So, I can catch up on sleep tonight. I don't have to be anywhere tomorrow, so it's a good opportunity to actually sleep for once. Whatever the case, I hope I'll be able to fall asleep and stay asleep. We will see what happens.

Temptation Bible vs Book of Mormon

In the Bible in 1 Corinthians 10:13 we find: There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able ; but will with the temptation also make a way to escape, that ye may be able to bear it. But what might seem as a contradiction is found in Alma 13:28 But that ye would humble yourselves before the Lord, and call on his holy name, and watch and pray continually, that ye may not be tempted above that which ye can bear , and thus be led by the Holy Spirit, becoming humble, meek, submissive, patient, full of love and all long-suffering; So, which is it? Either God tempts you to a point and stops, or you have to actively pray not to be tempted beyond that no return point. Which is it?

An Opposition In All Things

Long has been the story told about how there must be an opposition in all things. From the pre-existence there was Satan, Lucifer the Son of the Morning. In the beginning we were with God in his presence. We learned all we could while there. Until the moment we couldn’t progress any more, we were unable to become like God. So, we were given the opportunity to come to Earth to gain a body. A Savior would be provided to atone for our sins enabling us to come back to the presence of God. The idea that an opposition must be in all things comes from 2nd Nephi: For it must needs be, that there is an opposition in all things. If not so, my firstborn in the wilderness, righteousness could not be brought to pass, neither wickedness, neither holiness nor misery, neither good nor bad. Wherefore, all things must needs be a compound in one; wherefore, if it should be one body it must needs remain as dead, having no life neither death, nor corruption nor incorruption, happiness nor misery, neither...
