用java创建一个学生类，属性包括：学号、姓名，和Java、C语言、数据结构三门课程成绩 //使用ArrayList<Student>保存10个学生对象， //分别对这些学生按照Java、C语言、数据结构和总成绩进行排序 //lamda //Comparable compare(Object o1,Object o2)。最后要求写到一个.java中

好的，下面是代码实现：

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;

public class Student implements Comparable<Student>{
    private String id;
    private String name;
    private int javaScore;
    private int cScore;
    private int dataStructureScore;

    public Student(String id, String name, int javaScore, int cScore, int dataStructureScore) {
        this.id = id;
        this.name = name;
        this.javaScore = javaScore;
        this.cScore = cScore;
        this.dataStructureScore = dataStructureScore;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getJavaScore() {
        return javaScore;
    }

    public void setJavaScore(int javaScore) {
        this.javaScore = javaScore;
    }

    public int getCScore() {
        return cScore;
    }

    public void setCScore(int cScore) {
        this.cScore = cScore;
    }

    public int getDataStructureScore() {
        return dataStructureScore;
    }

    public void setDataStructureScore(int dataStructureScore) {
        this.dataStructureScore = dataStructureScore;
    }

    @Override
    public int compareTo(Student o) {
        return this.id.compareTo(o.getId());
    }

    public static void main(String[] args) {
        ArrayList<Student> students = new ArrayList<>();
        students.add(new Student("001", "Tom", 80, 90, 70));
        students.add(new Student("002", "Jerry", 70, 85, 90));
        students.add(new Student("003", "Mike", 90, 60, 80));
        students.add(new Student("004", "Lily", 60, 80, 85));
        students.add(new Student("005", "Lucy", 85, 70, 75));
        students.add(new Student("006", "John", 75, 90, 65));
        students.add(new Student("007", "Amy", 95, 75, 80));
        students.add(new Student("008", "Bob", 70, 85, 95));
        students.add(new Student("009", "Kate", 80, 75, 90));
        students.add(new Student("010", "Sam", 85, 80, 70));

        // 按照Java成绩排序
        Collections.sort(students, (o1, o2) -> o2.getJavaScore() - o1.getJavaScore());
        System.out.println("按照Java成绩从高到低排序：");
        for (Student student : students) {
            System.out.println(student.getId() + " " + student.getName() + " " + student.getJavaScore());
        }

        // 按照C语言成绩排序
        Collections.sort(students, Comparator.comparingInt(Student::getCScore).reversed());
        System.out.println("按照C语言成绩从高到低排序：");
        for (Student student : students) {
            System.out.println(student.getId() + " " + student.getName() + " " + student.getCScore());
        }

        // 按照数据结构成绩排序
        Collections.sort(students, Comparator.comparingInt(Student::getDataStructureScore).reversed());
        System.out.println("按照数据结构成绩从高到低排序：");
        for (Student student : students) {
            System.out.println(student.getId() + " " + student.getName() + " " + student.getDataStructureScore());
        }

        // 按照总成绩排序
        Collections.sort(students, (o1, o2) -> {
            int total1 = o1.getJavaScore() + o1.getCScore() + o1.getDataStructureScore();
            int total2 = o2.getJavaScore() + o2.getCScore() + o2.getDataStructureScore();
            return total2 - total1;
        });
        System.out.println("按照总成绩从高到低排序：");
        for (Student student : students) {
            System.out.println(student.getId() + " " + student.getName() + " " + (student.getJavaScore() + student.getCScore() + student.getDataStructureScore()));
        }
    }
}

以上代码实现了一个学生类，包含学号、姓名、Java成绩、C语言成绩、数据结构成绩等属性，使用ArrayList保存了10个学生对象，并分别按照Java、C语言、数据结构和总成绩进行排序。其中，使用lamda表达式和Comparator接口实现了按照Java、C语言、数据结构成绩排序，使用Comparable接口实现了按照学号排序，最后使用lamda表达式实现了按照总成绩排序。
