[程序员] 在 idea 中执行与在命令行执行，速度怎么相差这么大

public class Main {
public static void main(String[] args) {
long startTime = System.nanoTime();
long startTime2 = System.currentTimeMillis();
for (int i = -1; ++i < 1000; ) {
String row = "Column 1: " + "1" + ", Column 2: " + "2" +
", Column 3: " + "3" + ", Column 3: " + "4";
System.out.println(row);
}
long endTime = System.nanoTime();
long endTime2 = System.currentTimeMillis();

long durationInMillis = (endTime - startTime) / 1_000_000;
long durationInMillis2 = (endTime2 - startTime2) / 1;
System.out.println("Time taken to output the result: " + durationInMillis + " milliseconds");
System.out.println("Time taken to output the result: " + durationInMillis2 + " milliseconds");
}
}
