you convert an ArrayList to HashMap or LinkedHashMap, depending upon the scenario, so the problem ofconverting a List to Mapis actually the same as the problem of converting anArrayListtoHashMaporLinkedHashMapbecauseArrayListis a List and HashMap is a Map. I'll show you an example of this...
LinkedHashMap only stores Unique values, that is duplicate values are not allowed. LinkedHashMap maintains order, which means it returns the key value pair in the order in which they have been added. LinkedHashMap similar to HashMap allows null key and null value in it,but with a restricti...
