Start :^^ ^b^Stop 首部的分隔符革出一个空位,尾部分隔符没有革出空位. 这里的空位不是空格.参看3 和 4. 2. 1 public static voidmain(String args[]) { 2 String Str = new String("aaa"); 3 System.out.println("Start :"); 4 5 for (String retval: Str.split("a")) { 6 System.out....
使用StringTokenizer:对于简单的分隔符,StringTokenizer可能更快。 性能分析:使用 JMH(Java Microbenchmark Harness)进行更精确的基准测试。 旅行图 最后,以下是实现这个过程的旅程图,使用 mermaid 语法表示: Me Create Project Create a new Java project Write Code Write test code using split method Measure Perform...
The split() method splits a string into an array of substrings using a regular expression as the separator.If a limit is specified, the returned array will not be longer than the limit. The last element of the array will contain the remainder of the string, which may still have ...
Concatenate any number of strings. The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' """pass 看了构造就知道函数内需要传入可迭代对象,所以我们先传入一个列表演示...

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead. 参考:https://docs.oracle.com/en/java/javase...
