Using System.out
or System.err
rather than a dedicated logging facility makes it difficult to monitor the behavior of the program.
Example 1: The first Java program that a developer learns to write often looks like this:
public class MyClass
public static void main(String[] args) {
System.out.println("hello world");
}
}
System.out.println()
.System.out
or System.err
may indicate an oversight in the move to a structured logging system.
