我有这个代码，我想知道String args []在这里是什么意思以及它如何用作输入我阅读了许多在线评论但仍然对此感到困惑
static int parse_commandline(String args[]) {
// TODO range check
if (args.length == 0) {
System.err.println("No options are specified.");
System.err.println("Try `--help' for more information.");
System.exit(1);
}
Options options = new Options();
options.addOption("r", "tries", true, "# number of independent trials");
options.addOption("s", "tours", true, "# number of steps in each trial");
options.addOption("t", "time", true, "# maximum time for each trial");
options.addOption("seed", true, "# seed for the random number generator");}
