java run terminal command

### running terminal commands in java

#### 1. using `processbuilder`

`processbuilder` is the preferred way to create and manage operating system processes. it provides more control over the process and its environment.

**example: listing files in a directory**

here's how to use `processbuilder` to execute a terminal command that lists files in a directory.

#### explanation:
- `processbuilder` is initialized with the command `ls -l`, which is the command to list files in long format on unix-like systems.
- the error stream is redirected to the output stream to handle errors more easily.
- the process is started, and we read its output using a `bufferedreader`.
- finally, we wait for the process to complete and print its exit code.

#### explanation:
- similar to the `processbuilder` example, we read the output and wait for the process to finish.

### important points to consider

1. **cross-platform compatibility**: the command you use may vary between operating systems. for instance, `ls -l` works on unix/linux, while you might use `dir` on windows. you should handle this in your code if you want cross-platform support.

2. **error handling**: always ensure you handle exceptions properly. you can also read from the error stream if necessary for diagnostics.

3. **process management**: it's important to ensure that you wait for the process to finish and clean up resources, which is done using `waitfor()` in the examples above.

4. **security considera ...
