为什么它总是给我一个系统包错误？

Question

我不断收到错误，Java 没有.class为该文件创建文件，而是在命令提示符下给出错误

public class TotalAndAverage {

public static void main (String[] arg) {

    final int count = 6;

    double score0 = 98.05;

    double score1 = 100.00;

    double score2 = 80.50;

    double score3 = 62.65;

    double score4 = 77.25;

    double score5 = 90.93;

    double total = score0 + score1 + score2 + score3 + score4 + score5;

    double average = total/count;

    int averageInt = (int)average;

    int average2Digit = (int)(average * 100) - averageInt *100;

    System.out.println("Total Score is: \t" + total);

    System.out.println("Average is \t" + average);

    system.out.println("Average Score is: \t" + averageInt + "." + average2Digit);

}

}

表明

错误：包系统不存在

Answer 1

最后一行应该是System.out.println(.....)不system。

Answer 2

当你说something.somethingElse编译器假设你正在做一个packageName.classname顺便说一句，system.out.println("Average Score is: \t" + averageInt + "." + average2Digit);将system零件作为系统。
