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
