学生成绩管理系统设计实现

public static void main(String[] args) {
    Scanner sc = new Scanner(System.in);
    String[] names = new String[4];
    double[] scores = new double[names.length];
    for(int i = 0;i<4;i++){
        System.out.println("请输入学生姓名：");
        names[i] = sc.next();
        System.out.println("请输入成绩：");
        scores[i] = sc.nextInt();
    }
    while(true){
        System.out.println("请输入学生姓名");
        String name = sc.next();
        if(name.equals("esc")){
            break;
        }
        int index = -1;
        for(int i = 0;i< names.length;i++){
            if(name.equals(names[i])){
                index = i;
                break;
            }
        }
        if(index>=0){
            System.out.println(name+"的成绩是"+scores[index]);
        }else{
            System.out.println("查无此人");
        }
    }
