Java 将字符串分成三部分

Question

我需要将字符串拆分为 3 个部分。示例：

String s="a [Title: title] [Content: content]";

结果应该是：

s[0]="a"; 
s[1]="Title: title"; 
s[2]="Content: content";

稍后我想将 Title: title 和 Content: content 作为字符串键值对放在 Map 中。

Answer 1

你可以这样做，

String s = "a [Title: title] [Content: content]";
String parts[] = s.split("\]?\s*\[|\]");
System.out.println(Arrays.toString(parts));

或

String s = "a [Title: title] [Content: content]";
String parts[] = s.split("\s(?![^\[\]]*\])");  # Splits the input according to spaces which are not present inside the square brackets
ArrayList<String> l = new ArrayList<String>();
for (String i: parts)                              # iterate over the array list elements.
{
    l.add(i.replaceAll("[\[\]]", ""));           # replace all [, ] chars from the list elements and append it to the declared list l
}
System.out.println(l);

输出：

[a, Title: title, Content: content]
