The getKey() and getValue() methods of the Map may be used to repeatedly iterate via the key-value pairs in a TreeMap in Java.interface for entry. When the map keys and values are required in the loop, this method is frequently used and advised.getKey()...
Step 3 Obtain the entry set from the linkedHashMap using the entrySet() method and store it in the "entrySet" variable. Step 4 Create an iterator using the iterator() method on the entrySet. Step 5 Iterate through the LinkedHashMap entries using a while loop. Step 6 In the loop, take...
