How to Get Value of HashMap in Java?<\/p>\n

HashMap is a commonly used data structure in Java that allows you to store and retrieve key-value pairs. Retrieving the value associated with a specific key in a HashMap can be done using various methods provided by the Java Collections framework. In this article, we will explore different approaches to get the value of a HashMap in Java.<\/p>\n

The most straightforward way to obtain the value for a given key in a HashMap is by using the `get()` method. The `get()` method takes the key as its parameter and returns the value associated with that key. By calling this method on the HashMap object, you can easily retrieve the desired value.<\/p>\n

**How to get value of HashMap in Java?**<\/p>\n

To get the value associated with a specific key in the HashMap, you can use the `get()` method, as shown in the example below:<\/p>\n

“`java
\nHashMap hashMap = new HashMap<>();
\nhashMap.put(“apple”, 20);
\nhashMap.put(“banana”, 15);
\nhashMap.put(“orange”, 10);<\/p>\n

Integer value = hashMap.get(“apple”);
\nSystem.out.println(“Value: ” + value);
\n“`<\/p>\n

This code snippet demonstrates how to retrieve the value associated with the key “apple” from the HashMap. When executed, it will print “Value: 20” as output, indicating that the value of the “apple” key is 20.<\/p>\n
