Java, check if an executable exists in PATH environment
environment-variables, java
Solution
You can use `Runtime.getRuntime().exec("command");` in `try ... catch` section. If app won't be in `PATH` you will get an exception.
[EDIT]
But .. this will execute app instead of check. Sorry.
Problem
I can print the path using `System.getenv("PATH")`. Then I probably can traverse those paths and use `File` to check if the file is exist. Is there any faster way in Java ?
