Returns the last component of the vector. Returns an iterator over the elements in this list in a proper sequence. Inserts the specified object as a component in this vector at the specified index. The following example uses Jackson Core and Jackson Binding to convert Java Map to JSON. We will be using Jackson, Gson and org.json libraries. In this post, we look at 3 different examples to convert Java Map to JSON. Returns the index of the first occurrence of the specified element in this vector, searching forwards from the index, or returns -1 if the element is not found. It is quite common to convert Java Arrays and Maps into JSON and vice versa. Or -1 if this vector does not contain the element. Returns the index of the first occurrence of the specified element in this vector, Returns the hash code value for this Vector. In Java 8, you get the stream, which allows you to apply many functional programming operators like the map, reduce, and filter. Returns the element at the specified position in this Vector. Performs the given action for each element of the Iterable until all elements have been processed or the action throws an exception. Returns the first component (the item at index 0) of this vector. Increases the capacity of this vector, if necessary, to ensure that it can hold at least the number of components specified by the minimum capacity argument.Ĭompares the specified Object with this Vector for equality. Returns an enumeration of the components of this vector. Returns the component at the specified index. use: Map mapForIP aggregator.Returns true if this Vector contains all of the elements in the specified Collection.Ĭopies the components of this vector into the specified array. Returns true if this vector contains the specified element. Constructs a vector containing the elements of the specified collection, in the order they are retur add addElement. Removes all of the elements from this Vector. Returns the current capacity of this vector. Insert all of the elements in the specified Collection into this Vector at the specified position.Īdds the specified component to the end of this vector, increasing its size by one. Inserts the specified element at the specified position in this Vector.Īppends all of the elements in the specified Collection to the end of this Vector, in the order that they are returned by the specified Collectionâs Iterator.
