JAVA中,寫的Person類的class Person這行提示了The type Person is already defined.的錯(cuò)誤,是什么情況?
class Person {
\x05private String name;
\x05private int age;
\x05public void setName(String n) {
\x05\x05name = n;
\x05}
\x05public void setAge(int a) {
\x05\x05age = a;
\x05}
\x05public String getName() {
\x05\x05return name;
\x05}
\x05public int getAge() {
\x05\x05return age;
\x05}
\x05public void tell() {
\x05\x05System.out.println(getName());
\x05}
}
public class Ccl {
\x05public static void main(String[] args) {
\x05\x05Person per = new Person();
\x05\x05per.setName("Martin");
\x05\x05per.setAge(30);
\x05\x05per.tell();
\x05}
}
提示錯(cuò)誤,可以運(yùn)行,但是不管tell()里面的輸出內(nèi)容有幾個(gè),輸出結(jié)果都是Name:MartinAge:30
