Как добавить 100 в список элементов массива
В строке 4: я не могу понять, как сделать так, чтобы массив anArray добавлял 100 к каждому элементу после индекса 0 в цикле for? Инструкции приведены в комментарии. Есть предложения?
public static void main(String[] args) { // LINE 1. DECLARE AN ARRAY OF INTEGERS int[] anArray; // LINE 2. ALLOCATE MEMORY FOR 10 INTEGERS WITHIN THE ARRAY. anArray = new int[10]; // Create a usable instance of an input device Scanner myInputScannerInstance = new Scanner(System.in); // We will ask a user to type in an integer. Note that in this practice // code WE ARE NOT VERIFYING WHETHER THE USER ACTUALLY // TYPES AN INTEGER OR NOT. In a production program, we would // need to verify this; for example, by including // exception handling code. (As-is, a user can type in XYZ // and that will cause an exception.) System.out.print("Enter an integer and hit Return: "); // Convert the user input (which comes in as a string even // though we ask the user for an integer) to an integer int myFirstArrayElement = Integer.parseInt(myInputScannerInstance.next()); // LINE 3. INITIALIZE THE FIRST ARRAY ELEMENT WITH THE CONVERTED INTEGER myFirstArrayElement anArray[0] = myFirstArrayElement; // LINE 4. INITIALIZE THE SECOND THROUGH THE TENTH ELEMENTS BY ADDING 100 TO THE EACH PRECEDING VALUE. // EXAMPLE: THE VALUE OF THE SECOND ELEMENT IS THE VALUE OF THE FIRST PLUS 100; // THE VALUE OF THE THIRD ELEMENT IS THE VALUE OF THE SECOND PLUS 100; AND SO ON. for (int j=0; j < anArray.length; j++) { if (anArray[j]!= anArray[0]){ anArray[j] += 100; } } // LINE 5. DISPLAY THE VALUES OF EACH ELEMENT OF THE ARRAY IN ASCENDING ORDER BASED ON THE MODEL IN THE TOP-OF-CODE COMMENTS. Arrays.sort(anArray); // Send our Anarray array to be sorted in ascending order by the sort() method int i; // Define the counter for the loop. We can do it this way or inside // the for loop, as we did in the preceding for loop. for (i=0; i < anArray.length; i++) { // Loop, starting at 0 and adding 1 each time, until counter is less than array length. System.out.println("Element at index " + i + ": " + anArray[i]);// print the numbers } } }
Что я уже пробовал:
Я сделал все остальное для кода. Я не могу понять строку 4. пожалуйста, помогите. Спасибо.

anArray[0] = myFirstArrayElement;
anArray[1] = ?
