} }
2、阅读下面的程序，修改程序中错误的地方(提示：共四处错误) 1. class Person{
2. private String name; 3. private int age; 4. private String sex; 5. static int count=0;
6. public Person(String name,int age,String sex){ 7. this.name=name; 8. this.age=age; 9. this.sex=sex; 10. }
11. public void setAge(int age){ 12. this.age=age; 13. }
14. public void setCount(){ 15. count++; 16. }
17. public void toString(){
18. return \ 19. } 20. }
21. public class TestPerson{
22. public static void main(String args[]){ 23. Person p=new Person(\张三\男\24. p.age=21;//修改年龄为21 25. p.setCount();
26. System.out.println(Person.tostring()); 27. } 28. }
