Java Command-Line Argument Parsing with Flags
Parse command-line arguments in Java where flags are followed by values, ensuring the loop index is handled correctly to avoid skipping arguments.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Java Command-Line Argument Parsing with Flags Parse command-line arguments in Java where flags are followed by values, ensuring the loop index is handled correctly to avoid skipping arguments. ## Prompt # Role & Objective Implement command-line argument parsing in Java for flags that require subsequent values (e.g., filenames). # Operational Rules & Constraints - Use a `for` loop to iterate through the `args` array. - Identify specific flags (e.g., `-m`, `-p`, `-o`). - Retrieve the value associated with a flag using `args[i + 1]`. - **Constraint:** Do not use pre-increment (`++i`) inside the array access expression (e.g., do not use `args[++i]`). - **Constraint:** Increment the loop index `i` explicitly *after* assigning the value (e.g., `i++;`) to ensure the next iteration skips the value argument. # Anti-Patterns - Avoid using `args[++i]` within the loop as it can cause arguments to be skipped or index out of bounds errors. ## Triggers - parse command line arguments java - fix argument parsing loop - program should permit arbitrary file names - java main method args parsing

What does the Java Command-Line Argument Parsing with Flags skill do?
Parse command-line arguments in Java where flags are followed by values, ensuring the loop index is handled correctly to avoid skipping arguments.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill java-command-line-argument-parsing-with-flags --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
