In this section, we will learn what the String getChars() method is and how to use it in Java.

What is Java String getChars() Method?

The `getChars()` method is used to copy the characters of a string into a char array.

Basically, using this method, we can get the characters of a string value in an array of characters.

Java getChars() Method Syntax:

public void getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin)

getChars() Method Parameters:

• `srcBegin`: the first argument of this method is the index number of the source string from which we want to start copying the characters into the target array.
• `srcEnd`: the second argument is the excluding index number in which we want the copying characters to stop at that index.
• `dst`: the third argument is the address of the target array in which the characters should be stored in.
• `dstBegin`: this last argument is the index number of the target array in which we want the characters to be stored from that index forward.

getChars() Method Return Value:

This method does not return a value.

Example: using String getChars() method

public class Simple {

    public static void main(String[] args)  {
        String s1 = "BE KING TO ONE ANOTHER";

        char[] chars = new char[s1.length()];

        s1.getChars(0,s1.length(),chars, 0);

        for(char c: chars){
            System.out.print(c+", ");
        }
    }
}

Output:

B, E, , K, I, N, G, , T, O, , O, N, E, , A, N, O, T, H, E, R,
