by using local variables or java.lang.ThreadLocal

Tasneem K · Answer

import java.util.concurrent.atomic.AtomicInteger; public class MyCounter { private static AtomicInteger counter = new AtomicInteger(0); public static int getCount() { return counter.getAndIncrement(); } }In this particular counter example, we actually can make count++ atomic by using AtomicInteger from the package "java.util.concurrent.atomic".

Some other useful facts about thread-safe

Local variables are thread safe in Java.

Each thread has its own stack. Two different threads never shares the same stack. All local variables defined in a method will be allocated memory in stack. As soon as method execution is completed by the current thread, stack frame will be removed.
