mainの引数取得がすごく煩わしい.java

public class ArgsPicker {
	private int i = 0;
	private final String[] args;

	public ArgsPicker(String[] args) {
		this.args = args;
	}

	public String nextArg(String defaultValue) {
		String result = defaultValue;
		if (args != null) {
			if (args.length > i) {
				result = args[i++];
			}
		}
		return result;
	}
}
