System

Learn to interact with system-related information.

The System class provides methods for interacting with system-related information. Such as current time, system environment, system user, path, etc.

Methods

currentTimeMillis():

Returns the current time in milliseconds as a number.

// Example: Get current time in milliseconds
var currentTimeMillis = System.currentTimeMillis();
return "Current time in milliseconds: " + currentTimeMillis;

nanoTime():

Returns the current value of the system's high-resolution time source in nanoseconds as a number.

// Example 1: Get current time in nanoseconds
var nanoseconds = System.nanoTime();
return "Current time in nanoseconds: " + nanoseconds;

lineSeparator():

Returns the platform-specific line separator as a string.

// Example: Get the system-dependent line separator
var lineSeparator = System.lineSeparator();

getenv():

Returns the system environment as a string.

// Get the system user
var username = System.getenv("USERNAME");

// Get the system path
varpath = System.getenv("PATH");

Additional environment variables accessible through getenv() include:

• "USERPROFILE": Path to the current user's profile directory.

• "TEMP" and "TMP": Paths to the temporary directory.

• "USERNAME": The username of the currently logged-in user.

• "COMPUTERNAME": Name of the computer.

• "OS": Information about the operating system.

• "SYSTEMROOT" or "WINDIR": Paths to the Windows system directory.

• "APPDATA": Path to the directory where application-specific data for the current user is stored.
