This example shows how you can use if..else to "open a door" if the user enters the correct code:ExampleGet your own Java Server int doorCode = 1337; if (doorCode == 1337) { System.out.println("Correct code. The door is now open."); } else { System.out.println("Wrong code....
5. Using Ternary Operator to Replace Simpleif-else We can also use theternary operatorinstead of a simpleif-elsestatement to make the code more concise and readable. Consider a simpleif-elsestatement that checks if a number is greater than or less than a value, and stores the value in a...

Every time a case falls through (doesn't include abreakstatement), add a comment where thebreakstatement would normally be. This is shown in the preceding code example with the/* falls through */comment. Everyswitchstatement should include a default case. Thebreakin the default case is redunda...
