Question

java编程 有没有人会这道题的 帮帮忙谢谢了

Answer 1

public class Student {

private String name;
private int score;

//无参构造方法
public Student() {
}
//有参构造方法
public Student(String name, int score) {
this.name = name;
this.score = score;
}

public String getName() {
return name;
}

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

public int getScore() {
return score;
}

public void setScore(int score) {
this.score = score;
}

@Override
public String toString() {
return "Student{" +
"name='" + name + '\'' +
", score=" + score +
'}';
}
}
//测试类
public class StudentTest {

public static void main(String[] args) {
//使用无参构造方法
Student stu1 = new Student();
stu1.setName("student1");
stu1.setScore(100);
//使用有参构造方法
Student stu2 = new Student("student2", 99);
System.out.println("[输出学生1]" + stu1);
System.out.println("[输出学生2]" + stu2);
}
}

Answer 2

public class Student {
public static void main(String[] args) {
Student student1 = new Student();
student1.setName("李四");
student1.setScore(70);
Student student2 = new Student("张三", 80);
System.out.println(student1);
System.out.println(student2);
}

private String name;
private double score;

public Student(String name, double score) {
this.name = name;
this.score = score;
}

public Student() {
}

public String getName() {
return name;
}

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

public double getScore() {
return score;
}

public void setScore(double score) {
this.score = score;
}

public String toString() {
return "姓名: " + this.name + ", 成绩: " + this.score;
}
}

Answer 3

class Student{

private String name;

private double score;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public double getScore() {

return score;

}

public void setScore(double score) {

this.score = score;

}

public Student() {}

public Student(String name, double score) {

super();

this.name = name;

this.score = score;

}

}

public class TestDemo {

public static void main(String[] args) {

Student stu1 = new Student();

stu1.setName("张三");

stu1.setScore(85);

System.out.println("姓名："+stu1.getName()+"，成绩："+stu1.getScore());

Student stu2 = new Student("李四",90);

System.out.println("姓名："+stu2.getName()+"，成绩："+stu2.getScore());

   }

}
