怎么也不显示
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[] {"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] );
}
}
你的数组是String类型,你给数组初始化,每一项都需要双引号,我上面这段代码你运行一下就没问题了 。
