10. // using java if-else
11. System.out.println("==== using java if-else ===");
12. checkNumber(5); // Output -> Positive
13. checkNumber(0); // Output -> Positive
14. checkNumber(-3); // Output -> Negative
15.  
16. // using java ternary operator
17. System.out.println("==== using java ternary operator ===");
18. checkNumberUsingTernary(5); // Output -> Positive
19. checkNumberUsingTernary(0); // Output -> Positive
20. checkNumberUsingTernary(-3); // Output -> Negative
21. }
22.  
23. // using java if-else

29. }
30. }
31.  
32. // using java ternary operator
33. private static void checkNumberUsingTernary(int number) {
34. String result = number >= 0 ? "Positive" : "Negative";
