阅读程序，判断有误的语句是：Student.java源代码：package entity;class Money{}public class Student {private String getSno() {return sno;}public void setSno(String sno) {}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public String getSclass() {return sclass;}public void setSclass(String sclass) {this.sclass = sclass;}String sno;String name;int age;String sex;String sclass;}Test.java源代码：package view;import entity.*;public class Test {public static void main(String[] args) {entity.Student s1= new Student();entity.Money m = new Money();}}
阅读程序，完成划线处代码，使得程序运行结果为3.Student.java源代码：package entity;public class Student {private Student(){}static int accessnum;public static int getAccessnum() {return accessnum;}public static void setAccessnum(int accessnum) {Student.accessnum = accessnum;}public static 1getStudent(){2；Student m=new Student();return m;}public int getSno() {return this.getSno();}public void setSno(String sno) {}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public String getSex() {return sex;}public void setSex(String sex) {this.sex = sex;}public String getSclass() {return sclass;}public void setSclass(String sclass) {this.sclass = sclass;}String sno;String name;int age;String sex;String sclass;}Test.java源代码：package view;import entity.*;public class Test {public static void main(String[] args) {entity.Student s1=3;Student.getStudent();Student.getStudent();System.out.println(entity.Student.getAccessnum());}}
