<\/span><\/h2>\nThe most common way to retrieve a value from a HashMap in Java is by using the `get()` method. This method allows you to retrieve a value based on a specified key. Here’s how it works:<\/p>\n
“`
\n\/\/ Create a new HashMap
\nHashMap ages = new HashMap<>();<\/p>\n\/\/ Add key-value pairs to the HashMap
\nages.put(“John”, 25);
\nages.put(“Sarah”, 30);
\nages.put(“Michael”, 35);<\/p>\n
\/\/ Retrieve a value based on a key
\nint johnAge = ages.get(“John”);
\nSystem.out.println(“John’s age is: ” + johnAge);
\n“`<\/p>\n
The `get()` method retrieves the value associated with the specified key (“John” in this example) and stores it in the `johnAge` variable.<\/b> You can then use the value as desired, such as printing it to the console.<\/p>\n
