Example usage for com.google.common.collect Lists newArrayListWithExpectedSize

Introduction

In this page you can find the example usage for com.google.common.collect Lists newArrayListWithExpectedSize.

Prototype

@GwtCompatible(serializable = true)
public static <E> ArrayList<E> newArrayListWithExpectedSize(int estimatedSize)

Document

Creates an ArrayList instance to hold estimatedSize elements, plus an unspecified amount of padding; you almost certainly mean to call #newArrayListWithCapacity (see that method for further advice on usage).
