Java错误 - .class预期

Question

我试图创建一个程序来读取学生姓名和标记的输入，然后在表单GUI输出中给出该学生的姓名和成绩，但在编译时仍然存在问题。

import javax.swing.*;
public class p
{ 

private static String getGrade(int mark)
{
    String grade;
    if (mark<50)
                grade="F";
              else if (mark<65)
                grade="P";
              else if (mark<75)
                grade="C";
              else if (mark<85)
                grade="D";
              else
                grade="HD";
     return grade;
}
public static void main (String []args)
{
    JOptionPane.showMessageDialog(null,"Welcome to the Mark Entry System");
    String studentName = JOptionPane.showInputDialog(null,"Enter student name:");    
    int mark =Integer.parseInt(JOptionPane.showInputDialog(null,"Enter mark for student (out of 100)"));
    String grade = getGrade(int mark);
    JOptionPane.showMessageDialog(null,"The grade for " + studentName + " is " + grade);

}
}

Answer 1

这里

String grade = getGrade(int mark); //Can't do this

传递一些int

String grade = getGrade(mark); //pass any integer you want
