We only have to define all the characters we’ll use to split the string. Calling thesplitmethod will divide theexamplestring into four names. 3. Conclusion In this article, we’ve seen different options for splitting an input string by multiple delimiters. First, we discussed a solution base...
**处理空字符串和连续的分隔符**: ```java public class SplitEmptyAndMultipleDelimiters { public static void main(String[] args) { String str = "a,,b,,c"; String[] parts = str.split(",+"); // 使用“,+”来处理连续的逗号 for (String part : parts) { System.out.println(part); }...
