![]() ![]() Returns the index of the first (last) occurrence of the specified character, searching forward (backward) from the specified index. It always pays to pay attention to these little edge cases. output path.substring(0, path.lastIndexOf('/', 1)) given how the doc says. This matches at a certain position in the string, namely at a position right after the text sentence without making that text itself part of the match. character and take a substring based on its position. If you just want to cut your string two places after the decimal point, you could just find the. Java substring () utility is a very powerful library if you want to perform multiple special operations on String. otherwise, default to the empty string (or some other value) If you want to use float formatting, you could parse your string as a float, and then use '.2f. Getting a substring from a string after a particular word. Java: Getting a substring from a string starting after a particular character. Ask Question Asked 8 years, 2 months ago. if the substring does occur within the string, set the values accordinglyĪfter = str.substring(position + substr.length()) How to grab substring after a specific word in java. SubSequence (): You can use the subSequence () method to extract part of a string. We have a text line that seems to define a variable between 2 parts. The syntax for this method is String.substring (startIndex, endIndex). To make the first answer more efficient - as it is my preferred answer - then, we would need to remember the position of the substring: final int position = str.indexOf(substr) As we begin, it is important to understand the input and output of the Java program. ![]() As such, I would much rather the first solution, since it works irrespective of the composition of the original substring. Also, since split will interpret its input as a regular expression we have to be wary of invalid regular expression syntax. Get the substring after a specific Character using String.split() This is a three-step process: Use the split() method to split the string on the character. Alternatively, you can use the str.split() method. However, note that substr() might not be supported on earlier versions of some browsers (esp. The afterCharacter function takes a string and a character as parameters and returns the part of the string after the specified character. However, note that substr() might not be supported on earlier versions of some browsers (esp. Which ensures that the returned array has at most two elements. String substring () The substring () method has two variants and returns a new string that is a substring of this string. AFAIK, both substring() and indexOf() are supported by both Mozilla and IE. To that end, if we only want the first one to be recognized, it would be safer to call split with a limit: String parts = str.split(substr, 2) It is noteworthy that the second answer not work if we have more than one occurrence of the substring. ![]() String after = str.substring(str.indexOf(substr) + substr.length()) ![]() String before = str.substring(0, str.indexOf(substr)) You can do this: String str = "123dance456" There are 12 characters with special meanings: the backslash \, the caret ^, the dollar sign $, the period or dot. Note that split's argument is assumed to be a regular expression, so remember to escape special characters if necessary. Use the appropriately named method String#split(). ![]()
