  public class Exercise18 {
  public static void main(String[] args) {
          LinkedList<String> c1= new LinkedList<String>();
          System.out.println("Original linked list: " + c1);
          // Replacing 2nd element with new value
          c1.set(1, "Orange");
          System.out.println("The value of second element changed.");
          System.out.println("New linked list: " + c1);

Java: Tips of the Day


Removes elements in an array until the passed function returns true. Returns the remaining elements in the array.

Loop through the array, using Arrays.copyOfRange() to drop the first element of the array until the returned value from the function is true. Returns the remaining elements.

public static int[] dropElements(int[] elements, IntPredicate condition) {
    while (elements.length > 0 && !condition.test(elements[0])) {
        elements = Arrays.copyOfRange(elements, 1, elements.length);
    return elements;
