How to copy the characters of a given String into an Array of characters using the Java getChars() method

In this video, we will talk about the getChars() method, which is useful when copying characters of a given String into an Array of characters. Now, let’s take an example to show you how this method works

String str = “I love programming”; We will need an Array in which we will store all the copied characters

char[] copied_characters = new char[10]; Now, let’s call out method

This method takes four parameters: • the first parameter is of type integer and it represents the index of the first character in the String to copy • the second parameter is of type integer and it represents the index of the last character in the String to copy • the third parameter represents the array of characters in which the characters from the String get copied • the fourth parameter represents the index position in the Array from where the copied characters will be pushed into array

str.getChars(5 , 9 , copied_characters , 0);

Let’s print the content of our array for(char content : copied_characters) { System.out.println(content); }

Let’s also note that, if • The first parameter if less than zero, the method will throw an exception • The second parameter is greater than the length of the String, the method will throw an exception • The third parameter is less than zero, the method will throw an exception • The fourth parameter is greater than the length of the Array, the method will throw an exception
