break vs exit
| Statement | Ends |
|---|---|
| break | switch or loop |
| System.exit(0) | whole program |
| exit(1) | on a problem |
Remember
| exit(0): normal end |
| Nothing after it runs |
Break did not end your program. Why not? Compare them. Break leaves only the switch or loop. System dot exit ends the whole program. Exit of one means a problem. Keep two points. Exit of zero is a normal end. Nothing after it runs.
