應該是這樣的

public?class?HelloWorld{
????public?static?void?main(String[]?args)?{
????????String?name="愛慕課";
????????char?sex='男';
????????int?num=18;
????????double?price=120.5;
????????boolean?isOK=true;
??System.out.println(name);
??System.out.println(sex);
??System.out.println(num);
??System.out.println(price);
??System.out.println(isOK);
?}
}
