Extracting a substring as an array of characters in Java
To extract a substring as an array of characters in Java, use the getChars() method.
Let’s say the following is our string and character array.
String str = "World is not enough!"; char[] chArr = new char[10];
Now, use the getChars() method to extract a substring.
str.getChars(13, 19, chArr, 0);
The above substring is an array of characters which can be displayed as shown in the complete example below −
Example
public class Demo {
public static void main(String[] args) {
String str = "World is not enough!";
char[] chArr = new char[10];
str.getChars(13, 19, chArr, 0);
for(char res: chArr) {
System.out.println(res);
}
}
}Output
