Create a Java program that simulates a basic counter. The counter should be incremented by multiple threads. Two $(2)$ threads per implementation. Implementations: $1.$ Use synchronized keyword to increment the counter and to display the value of the counter. $2.$ Use AtomicInteger from java.util.concurrent.atomic package to increment the counter and display its value. Ensure that the value of the counter is correctly displayed when incremented by multiple threads in both implementations.
