  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 = {"Oracle","PHP","Linux","Java","HTML"} ;

          

  // 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：" + subjects[3]  );

  }

  }

  你定义的是字符串类型，这样才行String[] subjects = {"Oracle","PHP","Linux","Java","HTML"};
