I have searched but could not find a way to print only single key, value pair for particular entry.
map.containsValue(value) or map.containsKey(key)
will only tell if particular value or key is available or not.
I want to print that particular key, value pair if (value is available)
In other link, They want to get the random value, if you do not know the key. Here I know key and value and want to print it for particular key and value.
Print from the HashMap Reference This is the most basic and easiest method to print out HashMap in java. Pass the HashMap reference to the System. out. println, and the HashMap will output the key-value of the elements enclosed in curly brackets.
There is no avalilable method in https://docs.oracle.com/javase/7/docs/api/java/util/Map.html to get Entity from map if there is any key or value available. Try below code if it help :
if (map.containsKey(key)) {
Object value = map.get(key);
System.out.println("Key : " + key +" value :"+ value);
}
