实验二学生类只能输出平均值

Question

您好，我想请问下我这个只能输出平均成绩调用其他方法没有输出该怎么办

​
public class Student {
    public  String name;
    public  String gender;
    public  int age;
    private  double score;
    public  double getScore(){
        return
                score;
    }
    public  void setScore(double score){

        this.score =score;
    }
    public  Student(String name,String gender,int age,double score) {
        super();
        this.name = name;
        this.gender = gender;
        this.age = age;
        this.score = score;
    }

    public String toString() {
        return "Student [name=" + name + ", gender=" + gender + ", age=" + age+ ", score=" + score + "]";}


    public  static void  display(Student[]stu){
        double sum = 0;
        for (int i=0;i<stu.length;i++){
            double s=stu[i].getScore();
            sum=sum+s;
        }
        double a = sum/stu.length;
      System.out.println("平均成绩为"+a);
   }
  public static void dp( Student[]stu){
       System.out.println("学生成绩汇总表");
       for(int i=0;i<stu.length;i++){
           System.out.print(stu[i]+"\n");

       }
   }
    public static void sort(Student[]stu){
        for (int i= 0;i<stu.length;){
            for (int j=i;j<stu.length;j++){
                if(stu[i].getScore()<stu[j].getScore()){
                    Student tem =stu[j];
                    stu[j]=stu[i];
                    stu[i]=tem;
                }
            }
        }
    System.out.println("成绩最好的"+stu[0].toString());
    System.out.println("成绩最差的"+stu[4].toString());

    }

    public static void main(String[] args) {
        Student[ ]stu =new Student[5];
        Student s1 =new Student("文津","女",20,95.5);
        Student s2 =new Student("文明","女",21,90.2);
        Student s3=new Student("文程·","男",22,89.1);
        Student s4=new Student("文化","女",19,93.3);
        Student s5=new Student("文完","女",21,97.4);
        stu[0]=s1;
        stu[1]=s2;
        stu[2]=s3;
        stu[3]=s4;
        stu[4]=s5;
        Student.display(stu);
        Student.sort(stu);
        Student.dp(stu);

    }
    }

该回答通过自己思路及引用到GPTᴼᴾᴱᴺᴬᴵ搜索,得到内容具体如下：
如果您只想输出平均成绩而不调用其他方法，可以将 dp 和 sort 方法的调用从 main 方法中删除，只保留 display 方法的调用，像这样：

public static void main(String[] args) {
    Student[] stu = new Student[5];
    Student s1 = new Student("文津", "女", 20, 95.5);
    Student s2 = new Student("文明", "女", 21, 90.2);
    Student s3 = new Student("文程·", "男", 22, 89.1);
    Student s4 = new Student("文化", "女", 19, 93.3);
    Student s5 = new Student("文完", "女", 21, 97.4);
    stu[0] = s1;
    stu[1] = s2;
    stu[2] = s3;
    stu[3] = s4;
    stu[4] = s5;
    Student.display(stu);
}

这样，运行程序后就只会输出平均成绩。如果您需要在程序中调用 dp 或 sort 方法，可以将它们单独调用，或者在 main 方法中重新编排它们的顺序，以便在适当的时候调用它们。
