方法名得括號(hào)得成對(duì)存在！?。。。?！

第一段方法的結(jié)尾少了一個(gè)大括號(hào)，一個(gè)又一個(gè)和public String isoddnumber（int num)對(duì)齊的大括號(hào)。

public String isoddnumber這個(gè)方法寫完后要用大括號(hào)括起來(lái)，然后再寫main函數(shù)，不要把main函數(shù)括到isoddnumber里面

public?class?Dog?{

????public?String?isoddnumber(int?num){
????????if(num%2==0){
????????????return?"雙數(shù)";
????????}else?{
????????????return?"奇數(shù)";
????????}
????}

????public?static?void?main(String[]?args)?{
????????int?a?=0;
????????Dog?dog?=?new?Dog();
???????String?l=?dog.isoddnumber(a);
????????System.out.println(a+"是"+l);
????}
}
