java:我不知道问题出在那？

import java.util.scanner;
public class ch2c1 {
public static void main(String[]args){
int firstGrade,secondGrade;
Scanner input=new Scanner(System.in);
System.out.println("Please input the 1st grade:");
firstGrade=input.nextInt();
Ststem.out.println("Please input the 2nd grade:");
secondGrade=input.nextInt();
system.out.println("The maximum grade is"
+((firstGrade > secondGrade)?firstGrade:secondGrade));
system.out.println("The minimum grade is"
+((firstGrade < secondGrade)?firstGrade:secondGrade));
System.out.ptintln("The average grade is"+((firstGrade+secondGrade)/2.0));
}
}
显示错误
ch2c1.java:1: cannot resolve symbol
symbol : class scanner
location: package util
import java.util.scanner;
^
ch2c1.java:5: cannot resolve symbol
symb

给你改好的代码，你自己仔细对照一下，研究一下：

import java.util.Scanner;

public class Ch2c1 {
public static void main(String[] args) {
int firstGrade, secondGrade;
Scanner input = new Scanner(System.in);
System.out.println("Please input the 1st grade:");
firstGrade = input.nextInt();
System.out.println("Please input the 2nd grade:");
secondGrade = input.nextInt();
System.out.println("The maximum grade is"
+ ((firstGrade > secondGrade) ? firstGrade : secondGrade));
System.out.println("The minimum grade is"
+ ((firstGrade < secondGrade) ? firstGrade : secondGrade));
System.out.println("The average grade is"
+ ((firstGrade + secondGrade) / 2.0));
}
}

注意最基本的拼写，打好基础。

共勉！

Java 大小写敏感，显示7个错误，
第一个：import java.util.Scanner;这个会顺带解决第二处错误和第三处错误
第四个：System.out.println，567也都是一样的问题，全是拼写错误

你有好几个字都
