Example usage for com.google.common.collect Maps newHashMapWithExpectedSize

Introduction

In this page you can find the example usage for com.google.common.collect Maps newHashMapWithExpectedSize.

Prototype

public static <K, V> HashMap<K, V> newHashMapWithExpectedSize(int expectedSize)

Source Link

Document

Creates a HashMap instance, with a high enough "initial capacity" that it should hold expectedSize elements without growth.
