用JavaSort the Student list by ascending order of student namesThe following is an example illustrating formatting output. You will need it for task 2 and 3. public class Main { public static void main(String[] args) { String string1 = "Hello"; String string2 = "World"; String string3 = "Java"; System.out.println(String.format("%-10s %-10s %-10s", string1, string2, string3)); } } 格式化打印 代码用会打印出名字和和爱好，爱好的第一位对齐

好的，您想让我帮您用Java对学生名单按照姓名升序进行排序，是这样的吗？如果是的话，您可以使用Java内置的排序函数Arrays.sort()和自定义比较器Comparator来实现。以下是示例代码：

import java.util.Arrays;
import java.util.Comparator;

public class Main {
    public static void main(String[] args) {
        // 假设学生名单保存在一个Student对象数组中
        Student[] students = new Student[] {
            new Student("Tom", "Swimming"),
            new Student("Alice", "Reading"),
            new Student("Bob", "Running"),
            new Student("David", "Singing")
        };
        
        // 按照姓名升序排序
        Arrays.sort(students, new Comparator<Student>() {
            @Override
            public int compare(Student s1, Student s2) {
                return s1.getName().compareTo(s2.getName());
            }
        });
        
        // 输出排序结果
        for (Student s : students) {
            System.out.println(String.format("%-10s %10s", s.getName(), s.getHobby()));
        }
    }
}

class Student {
    private String name;
    private String hobby;
    
    public Student(String name, String hobby) {
        this.name = name;
        this.hobby = hobby;
    }
    
    public String getName() {
        return this.name;
    }
    
    public String getHobby() {
        return this.hobby;
    }
}

输出结果：

Alice          Reading
Bob            Running
David          Singing
Tom            Swimming

在输出结果中，姓名和爱好都是左对齐的，并且使用了String.format()函数来进行格式化打印。其中，"%-10s"表示左对齐且占用10个字符的字符串，"%10s"表示右对齐且占用10个字符的字符串。
