Convert a String to Character array in Java

Given a string, the task is to convert this string into a character array in Java.

Examples:

Input:  Hello World
Output:  [H, e, l, l, o,, W, o, r, l, d]

Input:  GeeksForGeeks
Output:  [G, e, e, k, s, F, o, r, G, e, e, k, s]

1. Method 1: Naive Approach
   • Step 1: Get the string.
   • Step 2: Create a character array of the same length as of string.
   • Step 3: Traverse over the string to copy character at the i’th index of string to i’th index in the array.
   • Step 4: Return or perform the operation on the character array.

   Below is the implementation of the above approach:

   
   

   
   
   

   // Java program to Convert a String // to a Character array using Naive Approach    import java.util.*;    public class GFG {        public static void main(String args[])     {         String str = "GeeksForGeeks";            // Creating array of string length         char[] ch = new char[str.length()];            // Copy character by character into array         for (int i = 0; i < str.length(); i++) {             ch[i] = str.charAt(i);         }            // Printing content of array         for (char c : ch) {             System.out.println(c);         }     } }
   Output:

   G
   e
   e
   k
   s
   F
   o
   r
   G
   e
   e
   k
   s
   

2. Method 2: Using toCharArray() Method
   • Step 1:Get the string.
   • Step 2:Create a character array of same length as of string.
   • Step 3:Store the array return by toCharArray() method.
   • Step 4:Return or perform operation on character array.
   
   

   
   
   

   // Java program to Convert a String // to a Character array using toCharArray()    import java.util.*;    public class GFG {        public static void main(String args[])     {            String str = "GeeksForGeeks";            // Creating array and Storing the array         // returned by toCharArray()         char[] ch = str.toCharArray();            // Printing array         for (char c : ch) {             System.out.println(c);         }     } }
   Output:

   G
   e
   e
   k
   s
   F
   o
   r
   G
   e
   e
   k
   s
