JAVA,10亿个数整除7个数,10亿次求余，编程语言性能测试

long startTime = System.nanoTime(); long c=0; for (int i = 0; i < 1000000000; i++) { if(i%7==0) c++; } long endTime = System.nanoTime(); long elapsedTime = endTime - startTime; double milliseconds = (double) elapsedTime / 1000000.0; System.out.print("用时毫秒："+milliseconds);
