Given the code fragment: class MySearch { public static void main(String[] args) { if (XXXX) { System.out.println("Found"); } } } Which code fragment, replace with XXXX, enables the code to print Foun

The `indexOf("com")` method returns the starting index of the substring "com" or -1 if not found. Comparing this result with `!= -1` yields a boolean true if "com" is present at any index, correctly fulfilling the condition for printing "Found".

In Java, an integer value returned by `indexOf()` cannot be implicitly converted to a boolean for an `if` statement; this would result in a compile-time type mismatch error.

This condition specifically checks if "com" is found exactly at index 19. If "com" exists at a different index or not at all, the condition would be false, failing to print "Found" in those valid "found" scenarios.

This statement attempts to compare an integer (the result of `indexOf()`) with a boolean literal (`false`), which is a type mismatch and will cause a compile-time error in Java.
