Java ProcessBuilder.command() is a method in the Java ProcessBuilder class that sets the command and arguments for a new process. It is used to specify the program to run and the parameters to pass to it. Introduced in Java 1997 with Java 1.1, command() is essential for launching and managing external processes in a Java application, particularly for automation tasks and system-level operations.
