Java类错误Main.Java:3:error:

我一直收到这个错误消息，我已经检查了我的文件名，我的公共类与我的.java文件相同。除了检查我不知道去哪里

Main.java:3: error: class ClassGenderPercentages is public, should be    declared in a file named ClassGenderPercentages.java
public class ClassGenderPercentages
   ^

这是我的密码

import java.util.Scanner;

public class ClassGenderPercentages

{
public static void main (String args[])
{

    Scanner keyboard = new Scanner(System.in);
    int maleStudents, femaleStudents;
    int totalStudents;
    double maleStudentPercentage, femaleStudentPercentage;

    maleStudents = keyboard.nextInt();
    System.out.println("Enter number of male registered:" + maleStudents);

    femaleStudents = keyboard.nextInt();
    System.out.println("Enter number of female registered:" + femaleStudents);


    totalStudents = (int) (maleStudents + femaleStudents);
    maleStudentPercentage = ((100 * maleStudents) / totalStudents);
    femaleStudentPercentage = ((100 * femaleStudents) / totalStudents);



    System.out.println("The percentage of males registered is: " + maleStudentPercentage + "%");
    System.out.println("The percentage of females registed is: " + femaleStudentPercentage + "%");
 }
}

您的文件名为Main.java，您的类ClassGenderPentages。 您可以将文件重命名为classgenderpentages.java

（您从编译器收到的错误中已经提到了这一点）

错误的可能副本明确指出，文件名应为classgenderpentages.java，而您的文件名为Main.java
