import com.google.common.collect.Maps; MapIn the above examples, the "Maps" class is imported from the "com.google.common.collect" package. The newHashMapWithExpectedSize method is then called, passing in the expected size of the HashMap as a parameter. Entries can then be added to the HashMap using the put method. Overall, the Maps newHashMapWithExpectedSize method is a useful tool in creating and optimizing HashMaps with a large number of entries, and is found in the com.google.common.collect package library in Java.myMap = Maps.newHashMapWithExpectedSize(500); myMap.put("apple", 10); myMap.put("banana", 5); myMap.put("orange", 15);
