Introduction<\/h3>\n

The linked list is one of the most crucial concepts and data structures to grasp while preparing for interviews. In a coding interview, having a thorough understanding of Linked Lists might be a major benefit.<\/p>\n<\/p>\n

The remove()<\/strong> method has two versions in Java’s List interface (which is implemented by ArrayList<\/strong> and LinkedList<\/strong>).<\/p>\n

Approach and Algorithm (remove(Object x))<\/h3>\n

Syntax:<\/strong> boolean remove(Object x)<\/p>\n

It accepts the object that is to be removed from the list. <\/p>\n

    \n
  • If it discovers and removes the element, it returns true. <\/li>\n
  • If the element to be removed isn’t present, it returns false.<\/li>\n<\/ul>\n

    If the element is present, it removes the first occurrence of the specified element from the given list. The specified list is not altered if the entry is not present.<\/p>\n

    After eliminating an element, it shifts any remaining items to the left and decreases their indexes by one.<\/p>\n

    Input<\/h4>\n

    [Coding, is, Fun], Element to be removed – \u201cis\u201d<\/p>\n

    Output<\/h4>\n

    [Coding, Fun]<\/p>\n

    Explanation<\/strong> – As we can see, the element to be removed from the list was \u201cis\u201d, and it has been removed from the given list. <\/p>\n

    Exceptions Thrown<\/h4>\n
      \n
    • If the type of the supplied element is incompatible with this collection, a ClassCastException<\/strong> will be thrown.<\/li>\n
    • If the provided element is null and this collection does not allow null elements, a NullPointerException<\/strong> will be thrown.<\/li>\n
    • If the remove operation is not supported by this collection, an UnsupportedOperationException<\/strong> will be thrown.<\/li>\n<\/ul>\n
