To convert an array to a Set in Java, you can use the Arrays.asList() method to create a List from the array, and then use the List.toSet() method to create a Set from the List. Here is an example of how to convert an array to a Set: import java.util.Arrays; import java....
System.out.println(pair.getKey()+ " = " +pair.getValue()); it.remove();//avoids a ConcurrentModificationException} } 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()) {//...
