Java HashMap.compute() is a method in the Java HashMap class that computes a new value for the specified key using a remapping function. If the key is not already present, it is added to the map with the computed value. Introduced in Java 2014 with Java 8, compute() is commonly used in cases where a map's value needs to be recalculated based on its current value or some external input.
