what does this statment print?

system.out.printin(5 + "bc");

This statement will cause a compilation error because the correct syntax for printing is `System.out.println()`, not `system.out.printin()`. Additionally, there should be a space between the 5 and "bc".

The correct version of the statement would be:

```
System.out.println(5 + " bc");
```

This would print "5 bc" to the console.

The statement `system.out.printin(5 + "bc");` will produce a compilation error because `system.out.printin` is not a valid statement in Java. It should be `System.out.println` with an uppercase 'S' for 'System', 'o' for 'out', and 'n' for 'println'.
