Java编程题,关于类的,看图!

很简单，待我给你示范一下吧：

public class Student {
private String name;
private int age;
private char sex;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public char getSex() {
return sex;
}
public void setSex(char sex) {
this.sex = sex;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Student(String name, char sex, int age) {
super();
this.name = name;
this.sex = sex;
this.age = age;
}
public Student() {
}

public void show() {
System.out.println("name："+this.name+"\t age："+this.age+"\t sex："+sex);
}

public static void main(String[] args) {
Student stu = new Student("java",'妖',20);
stu.show();
System.out.println("静态方法只能访问静态成员'(成员变量和成员方法)。'");
}
}

这么简单还百度，没好好学吧 哎
