Consider the following program segment in which the statements are jumbled, choose the correct order of statements to check if a given word is Palindrome or not.
boolean palin(String w) { boolean isPalin; w = w.toUpperCase(); int l = w.length(); isPalin = false; // Stmt (1) for (int i = 0; i < l / 2; i++) { char c1 = w.charAt(i), c2 = w.charAt(l - 1 - i); // Stmt (2) if (c1 != c2) { break; // Stmt (3) isPalin = true; // Stmt (4) } } return isPalin; }A shopping website offers a special discount if the order ID has the sequence 555 anywhere in it. For example, 158545553031, 198555267140, …. .
Fill in the blanks (a) and (b) in the given Java Method to convert the order ID (a long integer) into a string and check if the sequence 555 is present in it.
void checkOrder(long oid) { String str = _______(a)_________; if(______(b)_______) { System.out.println("Special Discount Eligible: " + oid); } }
