How to delete all the values from the HashMap in Java

We can remove the values of HashMap in Java by using clear() method as follows:

import java.util.HashMap;

HashMap<Integer,String> map = new HashMap<>();

map.put(1,”Hello”);// add key-value pair

map.put(2,”Hi”);

System.out.println(“Before clear: ” + map); // {1=Hello, 2=Hi}

map.clear(); // remove all entries

System.out.println(“After clear: ” + map); // {}
