System.console() in Java provides a convenient way to interact with the console, allowing you to read text and passwords securely.System.console() returns null in environments where no console is available, such as in an integrated development environment (IDE) like Eclipse or IntelliJ.
import java.io.Console;
public class ConsoleExample {
public static void main(String[] args) {
Console console = System.console();
if (console == null) {
System.out.println("No console available");
return;
}
String input = console.readLine("Enter your name: ");
System.out.println("Hello, " + input + "!");
}
}
System.console() offers the ability to read passwords securely without echoing the entered characters on the console.
import java.io.Console;
public class PasswordExample {
public static void main(String[] args) {
Console console = System.console();
if (console == null) {
System.out.println("No console available");
return;
}
char[] passwordArray = console.readPassword("Enter your password: ");
String password = new String(passwordArray);
System.out.println("Password entered is: " + password);
}
}
