標題[問題] 求助inner class
時間Mon Mar 12 17:54:14 2012
剛剛碰到個關於inner class的問題..求解~__~"
像是這樣...
public class test {
public class person {
private String name;
public person() {
this("noname", 0);
}
public person(String name, int money) {
this.name = name;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
}
public static void main(String[] args) throws IOException {
BufferedReader f = new BufferedReader(new FileReader("test.in"));
int NP = Integer.parseInt(f.readLine());
person[] pe = new person[NP];
for (int index = 0; index < NP; index++) {
pe[index] = new person();
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
會有錯誤:No enclosing instance of type test is accessible. Must qualify the allocation
with an enclosing instance of type test (e.g. x.new A() where x is an
instance of test).
}
System.exit(0); // don't omit this!
}
}
不知道該怎麼解決= ="..把person class放在外面就沒這個問題，弄來裡面就會這樣 ..
咕狗過有看到不能這樣宣告，想請問一下這樣該怎麼解決嗎
