在Java中生成CPU负载

public class CpuLoadGenerator {
    public static void main(String[] args) {
        for (int i = 0; i < 10; i++) {
            new Thread(() -> {
                while (true) {
                    // 执行一些计算任务
                    double result = 0.0;
                    for (int j = 0; j < 1000000; j++) {
                        result += Math.sqrt(j);
                    }
                }
            }).start();
        }
    }
}

public class CpuLoadGenerator {
    public static void main(String[] args) throws IOException {
        ProcessBuilder processBuilder = new ProcessBuilder("ffmpeg", "-i", "input.mp4", "output.mp4");
        processBuilder.start();
    }
}
