Question

所以，我有以下情况：

private BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));

String line= reader.readLine();
String first = ?
String second = ?

所以，我知道用户会输入这样的东西：喜欢猫和狗。我希望第一个单词（在本例中为love）始终在String中，其他所有内容在String中。我怎样才能尽可能简单？

Answer 1

String line = "love cats and dogs";
// split into 2 parts
String[] parts = line.split(" ",2);

String first = parts[0];
String second = parts[1];

Answer 2

简单地：

int splitIndex = line.indexOf(" ");
String first = line.substring(0, splitIndex);
String second = line.substring(splitIndex + 1);
