看一下哪错了？
public class HelloWorld {
public static void main(String[] args) {
// 定义一个长度为5的字符串数组，保存考试科目信息
String[] subjects = new String[5];
// 分别为数组中的元素赋值
subjects[0] = "Oracle";
subjects[1] = "PHP";
subjects[2] = "Linux";
subjects[3] = "Java";
subjects[4] = "HTML";
System.out.println("数组中第4个科目为:" + subject[3]);
}
}
