這個哪里有問題
public class HelloWorld {
? ? public static void main(String[] args) {
? ? ? ??
// 定義一個長度為5的字符串數(shù)組，保存考試科目信息
String[] subjects = {0,1,2,3,4};
? ? ? ??
// 分別為數(shù)組中的元素賦值
subjects[0] = "Oracle";
subjects[1] = "PHP";
subjects[2] = "Linux";
subjects[3] = "Java";
subjects[4] = "HTML";
? ? ? ??
System.out.println("數(shù)組中第4個科目為：" +subjects[3]);
}
}

String[] subjects = {0,1,2,3,4};
這個句子定義的數(shù)字是subjects的元素
subjects[0] = "Oracle";
subjects[1] = "PHP";
subjects[2] = "Linux";
subjects[3] = "Java";
subjects[4] = "HTML";
而這五個句子里的數(shù)字代表數(shù)字元素的下標

你試試用new賦初值
