Here is an example that starts a process with a modified working directory and environment, and redirects standard output and error to be appended to a log file: ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2"); Map<String, String> env = pb.environment(); env.put...
For example: [23, "Saturn", java.sql.Connection@li734s] can be considered a tuple of three elements (a triplet) containing an Integer, a String, and a JDBC Connection object. License: Apache 2. Immutables - Java annotation processors to generate simple, safe and consistent value objects...
