To prevent conflicts when working with primitive data types in a multithreaded environment in Java, the following methods are used:

Synchronization (synchronized) — locking code or methods so that only one thread can execute the critical section at a time.
Classes from the java.util.concurrent.atomic package — for example, AtomicInteger, AtomicBoolean, which provide atomic operations without explicit synchronization.
Volatile — a keyword that guarantees visibility of variable changes between threads but does not ensure atomicity of complex operations.

Example of using AtomicInteger:

import java.util.concurrent.atomic.AtomicInteger;

public class Counter {
    private AtomicInteger count = new AtomicInteger(0);

    public void increment() {
        count.incrementAndGet();
    }

    public int getCount() {
        return count.get();
    }
}

This approach allows safe modification of primitive values in a multithreaded environment without locks.
