使用类变量进行多线程的最简单方法？

public class MyClass {
    private static int count = 0; // 静态变量

    public static synchronized void increment() {
        count++; // 对静态变量进行操作
    }

    public static void main(String[] args) {
        Thread thread1 = new Thread(new Runnable() {
            public void run() {
                for (int i = 0; i < 1000; i++) {
                    increment();
                }
            }
        });

        Thread thread2 = new Thread(new Runnable() {
            public void run() {
                for (int i = 0; i < 1000; i++) {
                    increment();
                }
            }
        });

        thread1.start();
        thread2.start();

        try {
            thread1.join();
            thread2.join();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println("Count: " + count); // 输出结果
    }
}
