用另一个[重复]替换字符串数组

Question

在开发 Android 项目时，我处于一个位置

就是这么简单

String[] subjects = {};
//It is a string array what I want transform by another
String[] another = {"Physics","Chemistry"};

如何用另一个主题替换主题

Answer 1

这样使用会有帮助

String[] subjects = {};
String[] another = {"Physics","Chemistry"};

subjects  = another.clone();

或第二个选项这样做

subjects   = Arrays.copyOf(another , another .length);

这会将您的另一个数组复制到您的主题数组
