The linked list is one of the most important concepts and data structures to learn while preparing for interviews. Having a good grasp of Linked Lists can be a huge plus point in a coding interview.<\/p>\n<\/p>\n
In this problem, we are given a LinkedHashMap. We will be learning about the LinkedHashMap removeEldestEntry() method. <\/p>\n
The Java method java.util.LinkedHashMap.removeEldestEntry() is used to keep track of whether the map removes any eldest entries. <\/p>\n
private boolean removeEldestEntry(Map.Entry eldest)<\/strong><\/p>\n If the eldest entry is to be deleted from the map, the map returns true; otherwise, the map returns false.<\/p>\n { [ 1 , \u201cCoding\u201d ] , [ 2, \u201cis\u201d ] , [3, \u201cfun\u201d ] }, Max size = 3<\/p>\n { [ 2, \u201cis\u201d ] , [ 3, \u201cfun\u201d ] , [ 4, \u201csuper\u201d ] }<\/p>\n As we can see, we have added a 4th<\/sup> key value pair to the LinkedHashMap, the eldest entry i.e [1 , \u201cCoding\u201d]<\/strong> gets removed as the maximum size allocated to the LinkedHashMap is 3.<\/p>\n look at the approach by referring the best sites to learn coding.<\/p>\n We will create a LinkedHashMap.Parameters<\/h4>\n
