In Java, thesplitmethod is commonly used to split a string into an array of substrings based on a specified delimiter. However, there are cases where we may want to extract the content before a particular character in a string. This can be achieved by using thesplitmethod along with other...
An alternative to processing the string directly would be to use a regular expression with capturing groups. This has the advantage that it makes it straightforward to imply more sophisticated constraints on the input. For example, the following splits the string into two parts, and ensures that ...
Stringstr="apple123banana456orange";String[]result=str.split("\\d+");// 匹配连续的数字//结果为["apple","banana","orange"] 4.处理包含空字符串的情况: Stringstr="apple,,banana,orange";String[]result=str.split(",");//结果为["apple","","banana","orange"] 5.处理以分隔符开头的情况:...
1.String[] split(String regex): It returns an array ofstrings after splitting an inputString based on the delimiting regular expression. 2.String[] split(String regex, int limit): This method is used when you want to limit the number of substrings. The only difference between this variant ...

1. Split String by Period / Dot Since the period or dot (.) is treated as a special character in regular expressions, you must escape it either with a double backslash (\\) or use the Pattern.quote() method: String animals = "Lion.Cheetah.Bunny"; // split string into an array Stri...
String(byte[] bytes, Charset charset) Constructs a new String by decoding the specified array of bytes using the specified charset. String(char[] value) Allocates a new String so that it represents the sequence of characters currently contained in the character array argument. String...
