When I serialize my LinkedHashMap<String, String> using GSON, I get {\"b\":\"a\",\"a\":\"1\",\"c\":\"2\"}
Does Colelction.unmodifiableMap safeguard the iteration order? I was trying newMap.put(key,Collections.ModifiableMap(oldMap))
How can I override removeEldestEntry method to saving eldest entry to file with help of FileOutputStream, DataOutputStream and writeObject(). Code.
I have a LinkedHashMap < String, String > map . List < String > keyList; List < String &开发者_运维百科gt; valueList;
I have the first key/value pair in a LinkedHashMap, which I get from a loop: for (Entry<String, String> entry : map.entrySet()) {
Looking at the JDK source code fo开发者_如何学Gor LinkedHashMap, I noticed that this class is declared as:
If LinkedHashMap\'s ti开发者_StackOverflowme complexity is same as HashMap\'s complexity why do we need HashMap? What are all the extra overhead LinkedHashMap has when compared to HashMap in Java?Link
So i want to pass a LinkedHashMap to an intent. //SEND THE MAP Intent singlechannel = new Intent(getBaseContext(),singlechannel.class);
i have a linkedhashmap and i need to permute (change the key of the values) between 2 random values example :
Suppose I have a Java method that 开发者_高级运维returns a HashMapobject. Because a LinkedHashMap is a subclass of HashMap, I can return a LinkedHashMap from this method just fine.
