2.If you're only interested in the keys, you can iterate through the "keySet()" of the map: Map<String, Object> map =...;for(String key : map.keySet()) {//...} 3.If you only need the values, use "value()": for(Object value : map.values()) {//...} ...
A linked list is a data structure that consists of a sequence of nodes, where each node stores an element and a reference to the next node. In Java, the
To iterate over an enum in Java using a for loop, you can use the values() method of the enum type to get an array of all the enum values, and then use a standard for loop to iterate over the array. For example, consider the following enum type: public enum Color { RED, GREEN,...
