  • Constructor Details

    • FloatArray

      public FloatArray()
      Creates a new expandable array with an initial capacity of 100.
    • FloatArray

      public FloatArray​(int initialCapacity)
      Creates a new expandable array with specified initial capacity.
      Throws:
      java.lang.IllegalArgumentException - if the specified initial capacity is less than zero
  • Method Details

    • size

      public int size()
      Returns the number of elements in the array.
    • clear

      public void clear()
      Removes all elements form this FloatArray.
    • toArray

      public float[] toArray()
      Returns a float array containing all elements of this FloatArray.
    • get

      public float get​(int index)
      Returns the element at the specified position in this FloatArray.
      Throws:
      java.lang.IndexOutOfBoundsException - - if index is out of range (index = size()).
    • getLast

      public float getLast()
      Returns the last element of this FloatArray.
      Throws:
      java.lang.IndexOutOfBoundsException - - if this FloatArray is empty
    • set

      public float set​(int index, float value)
      Replaces the element at the specified position with the value given.
      Returns:
      the value previously at the specified position.
      Throws:
      java.lang.IndexOutOfBoundsException - - if index is out of range (index = size()).
    • add

      public int add​(float value)
      Appends the specified value to the end of this FloatArray. Returns the number of elements after adding.
    • add

      public int add​(float[] a, int n)
      Appends the first n values from the specified array to this FloatArray. Returns the number of elements after adding.
    • removeLast

      public void removeLast​(int n)
      Deletes the last n element from this FloatArray. n may be larger than the number of elements; in that case, all elements are removed.
    • trimToSize

      public void trimToSize()
      Trims the capacity of this FloatArray instance to be its current size, minimizing the storage of the FloatArray instance.
