python dictionary equivalent in java

Sure, I'd be happy to provide you with an informative tutorial on Java's equivalent to Python dictionaries, which are called HashMaps in Java. HashMaps in Java provide key-value pairs, similar to Python dictionaries. Let's go through a step-by-step guide with code examples.
To create a HashMap in Java, you can use the following syntax:
Replace KeyType with the type of your keys and ValueType with the type of your values.
Example:
To add key-value pairs to the HashMap, you can use the put method.
Example:
To retrieve the value associated with a specific key, you can use the get method.
Example:
You can use the containsKey method to check if a specific key exists in the HashMap.
Example:
You can use a for-each loop to iterate over the key-value pairs in the HashMap.
Example:
To remove a key-value pair from the HashMap, you can use the remove method.
Example:
Java's HashMap provides a versatile and efficient way to store and retrieve key-value pairs, similar to Python dictionaries. You can use it to manage and organize data in your Java applications.
