Method Details

getFloat
public float getFloat(int i) Description copied from interface:FloatList
Returns the element at the specified position in this list. -
rem
public boolean rem(float k) Description copied from class:AbstractFloatCollection
Removes a single instance of the specified element from this collection, if it is present (optional operation).Note that this method should be called
remove()
, but the clash with the similarly named index-based method in theList
interface forces us to use a distinguished name. For simplicity, the set interfaces reinstatesremove()
