If you want a char[] (primitives) you can use a method which returns a char[]. src: public static char[] toCharArray(String input){ StringTokenizer stringTokenizer = new StringTokenizer(input, " "); char[] chars = new char[stringTokenizer.countTokens()]; for (int i = 0; i < chars.length; i++) chars[i] = stringTokenizer.nextToken().charAt(0 ...
The StringBuilder class contains getChars () method to convert StringBuilder to char array. The syntax of getChars () method is:- public void getChars (int start, int end, char [ ] destination, int deststart) Parameters:- Start: the index from where we need to start copying. End: the index from where we need to end the copy.

22 maj 2019 · The getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin) method of StringBuilder class copies the characters starting at the given index:srcBegin to index:srcEnd-1 from String contained by StringBuilder into an array of char passed as parameter to function.
In this tutorial, we will learn about the Java StringBuilder.getChars () function, and learn how to use this function to copy characters from this StringBuilder sequence to a destination array, in the specified source index range, with the help of examples.
The Java StringBuilder getChars() method copies the characters from this sequence into the destination character array dst. In Java, an array is an object that contains an element of similar data types.
The StringBuilder.getChars() method in Java is used for copying characters from a StringBuilder object into a destination character array. By understanding how to use this method, you can efficiently extract and manipulate subsequences of characters.
