I tried to split a string using string.Index and string.length but I get an error that string is out of range. How can I fix that?
while (in.hasNextLine()) { String temp = in.nextLine().replaceAll("[<>]", ""); temp.trim(); String nickname = temp.substring(temp.indexOf(' ')); String content = temp.substring(' ' + temp.length()-1); System.out.println(content);

Using the split() Method For example, if we put the limit as n (n >0), it means that the pattern will be applied at most n-1 times. Here, we'll be using space (” “) as a regular expression to split the String on the first occurrence of space.
To split a string and get the first element of the array, call the split() method on the string, passing it the separator as a parameter, and access the array element at index 0 . For example, str. split(',')[0] splits the string on each comma and returns the first array element. Copied!
split("-"); We can simply use a character/substring instead of an actual regular expression. Of course, there are certain special characters in regex which we need to keep in mind, and escape them in case we want their literal value. Once the string is split, the result is returned as an array of Strings.
split("\\s+") will split the string into string of array with separator as space or multiple spaces. \s+ is a regular expression for one or more spaces.
Use the java.lang.String split function with a limit.
String foo = "some string with spaces"; String parts[] = foo.split(" ", 2); System.out.println(String.format("cr: %s, cdr: %s", parts[0], parts[1])); You will get:
cr: some, cdr: string with spaces Must be some around this:
String nickname = temp.substring(0, temp.indexOf(' ')); String content = temp.substring(temp.indexOf(' ') + 1); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
