There are many ways to compareHashMaps in Java. We can compare them using theequals()method. The default implementation compares each value. If we change the inner Map’s contents, the equality check fails. If the inner objects are all new instances every time in the case of user-defined...
Examples Since the map created by this method is a view of the original map, modifying the original will reflect the changes in it: package com.logicbig.example.collections;import java.util.Collections;import java.util.HashMap;import java.util.Map;public class UnmodifiableMapExample { public ...
3.1. Creating Nested Map usingMap.put() We can useMapinterfaceput()method for adding elements in the outer as well as innerHashMap. Map<String,Map<String,String>>employeeMap=newHashMap<>();Map<String,String>addressMap=newHashMap<>();addressMap.put("Permanent","Florida");addressMap.put(...
