為什么這樣不行？
public class HelloWorld {
? ? public static void main(String[] args) {
? ? ? ??
// 定義一個(gè)長(zhǎng)度為5的字符串?dāng)?shù)組，保存考試科目信息
String[] subjects = {Oracle,PHP,Linux,Java,HTML};
? ? ? ??
System.out.println("數(shù)組中第4個(gè)科目為：" +subjects[3]);
}
}

你定義的是字符串類型，這樣才行String[] subjects = {"Oracle","PHP","Linux","Java","HTML"};
