Method from 'System.out' can be used instead of 'java.lang.IO'
Reports IO.println() and IO.print() calls and suggests replacing them with System.out methods.
This inspection helps migrate code from java.lang.IO class back to traditional System.out calls.
Example:
IO.println("Hello, World!");
After the quick-fix is applied:
System.out.println("Hello, World!");
