Individual characters of the sequence, for comparing strings, for The class String includes methods for examining Here are some more examples of how strings can be used: String buffers support mutable strings.īecause String objects are immutable they can be shared. Strings are constant their values cannot be changed after theyĪre created. String literals in Java programs, such as "abc", are We learned to split strings using different delimiters such as commas, hyphens, and even multiple delimiters in a String.The String class represents character strings. This Java String tutorial taught us to use the syntax and usage of Spring.split() API, with easy-to-follow examples. String str = "how to do in java provides java tutorials" After the method has found the number of tokens, the remaining unsplitted string is returned as the last token, even if it may contain the delimiters.īelow given is a Java program to split a string by space in such a way the maximum number of tokens can not exceed 5. This version of the method also splits the string, but the maximum number of tokens can not exceed limit argument. In the given example, I am splitting the string with two delimiters, a hyphen and a dot. Use regex OR operator '|' symbol between multiple delimiters. Java program to split a string with multiple delimiters. Java program to split a string by delimiter comma. To split by all white space characters (spaces, tabs etc), use the delimiter “ \\s+“. The following Java program splits a string by space using the delimiter "\\s". String str = "how to do-in-java-provides-java-tutorials" The following Java program splits a string based on a given delimiter hyphen "-". Exception in thread "main" Īt (String.java:2324)Īt (StringExample.java:11)Ģ. It will throw NullPointerException in case the method argument is null. The method does not accept ‘null’ argument. Exception in thread "main" 圎xception: Unclosed character class near index 0 1.3. In the given example, “ strArray = "hello world".split("[") Watch out that split() throws PatternSynta圎xception if the regular expression’s syntax is invalid. Public String split(String regex, int limit) 1.2. If the limit is negative then result array can be of any size.The trailing empty strings will be discarded. If the limit is zero then result array can be of any size.The result array’s length will be no greater than limit, and the array’s last entry will contain all input beyond the last matched delimiter. If the limit is positive then the pattern will be applied at most limit – 1 times.
