  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[]{"1","2","3","4","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：" +  subjects[3]  );

  }

  }

  String[] subjects =new String[]{0,1,2,3,4};

  应该改为

  String[] subjects =new String[5];
