This is a grade checking program where the user is supposed to input a grade 0-100 and it says what grade they got. Ive looked elsewhere but can't find anything.

Thanks in advance 

```
import java.util.*;

public class grading{
  public static void main(String[] args){
    Scanner scan = new Scanner(System.in);
    System.out.println("Please input grade");
    int grade = scan.nextInt();
    if (grade > 100){
      System.out.println("Sorry please put a number between 0-100");
    }
    else if (grade > 90){
      grade = "A";
      System.out.println("This student recieved " + grade " for his/her grade");
    }
    else if (grade > 75){
      grade = "B";
      System.out.println("This student recieved " + grade " for his/her grade");
    }
    else if (grade > 49){
      grade = "C";
      System.out.println("This student recieved " + grade " for his/her grade");
    }
    else{
      grade = "F";
      System.out.println("This student recieved " + grade " for his/her grade");
    }

  }

}
