Java 25 introduces simple IO methods, such as IO.println() and readln() to make interacting with the console more convenient. IntelliJ IDEA introduces two new live templates to use these methods: iop for println() and ior for readln().

In addition, there are quick-fixes available to convert IO.println() to System.out.println(), and vice versa. Invoke Context Actions ⌥⏎ (macOS) / Alt+Enter (Windows/Linux) on the method and select the option Replace with System.out.println() or Replace with IO.println().
