如何在同一语句中进行字母输入和浮点输入

Question

创建程序段，如果用户想接受教师的评估分数或评估信，该程序段将为用户提供帮助。打印教员的姓名和获得的备注。备注（rem）基于以下标准：（备注.java）

SCORE/LETTER        REMARKS
4.50-5.00 or A          Outstanding
4.00-4.49 or B          Very Satisfactory
3.50-3.99 or C          Satisfactory
3.00-3.49 or D          Needs Improvement
2.99    below or E          Poor

请帮助我如何输入要添加到if-else语句中的字母选项。

截至目前，这是我的程序：

Scanner in = new Scanner (System.in);
String n;
float score;

System.out.println("Enter Faculty's Name:");
n=in.nextLine(); //asking the user to incode his/her name
System.out.println("Enter score:");
score=in.nextFloat(); //asking the user to incode score

if ( score >=4.50  )//  4.50 to 5.00
    System.out.println("Remark: Outstanding");
else if(score>=4.00)// 4.00 to 4.49
    System.out.println("Remark: Very Satisfactory");
else if(score>=3.50)// 3.50 to 3.99
    System.out.println("Remark: Satisfactory");
else if(score>=3.00)//3.00 to 3.49
    System.out.println("Remark: Needs Improvement");
else
    System.out.println("Remark: Poor");

试试这个：

    Scanner in = new Scanner (System.in);
    String n, score;
    System.out.println("Enter Faculty's Name:");
    n=in.nextLine(); //asking the user to incode his/her name
    System.out.println("Enter score:");
    score=in.nextLine(); //asking the user to incode score
    if ("ABCDE".contains(score.toUpperCase())) {
        if (score.equalsIgnoreCase("a"))//  4.50 to 5.00
            System.out.println("Remark: Outstanding");
        else if(score.equalsIgnoreCase("b"))// 4.00 to 4.49
            System.out.println("Remark: Very Satisfactory");
        else if(score.equalsIgnoreCase("c"))// 3.50 to 3.99
            System.out.println("Remark: Satisfactory");
        else if(score.equalsIgnoreCase("d"))//3.00 to 3.49
            System.out.println("Remark: Needs Improvement");
        else
            System.out.println("Remark: Poor");
    } else {
        if (Float.valueOf(score) >=4.50)//  4.50 to 5.00
        System.out.println("Remark: Outstanding");
        else if(Float.parseFloat(score) >=4.00 )// 4.00 to 4.49
            System.out.println("Remark: Very Satisfactory");
        else if(Float.parseFloat(score) >=3.50 )// 3.50 to 3.99
            System.out.println("Remark: Satisfactory");
        else if(Float.parseFloat(score) >=3.00 )//3.00 to 3.49
            System.out.println("Remark: Needs Improvement");
        else
            System.out.println("Remark: Poor");            
    }
