- Given String value in java.
- We would like to convert String to char & char array using following methods.
- charAt method of String class returns character of String at specified index.
- toCharArray method of String class converts String to new character array
Example: convert String to char & char array in java
Example : Given inputString = "Java"//character at specified Indexchar at 0 index = 'J'char at 1 index = 'a'char at 2 index = 'v'char at 3 index = 'a'//Convert String to character array:Character array would be like = [J, a, v, a] |
Java methods of String class to convert String to char & char array
| Method Name | Description |
|---|---|
| char charAt(int index) | Returns the char value at the specified index. |
| char[] toCharArray() | Converts this string to a new character array. |
Program: Convert string to char & character array in java
package org.learn;import java.util.Arrays;public class ConvertStringToCharAndArray { public static void main(String[] args) { String strValue = "Java"; System.out.println("Input String : " + strValue); //Convert char to string using Character.toString System.out.println("Char at zero index : "+ strValue.charAt(0)); System.out.println("Char at 1 index : "+ strValue.charAt(1)); System.out.println("Char at 2 index : "+ strValue.charAt(2)); System.out.println("Char at 3 index : "+ strValue.charAt(3)); System.out.print("Print all characters using loop : "); //Loop through string & print all characters for(int index = 0; index < strValue.length(); index++) { System.out.print(strValue.charAt(index)); } //Convert String to char array char chArray[] = strValue.toCharArray(); System.out.println("\nString to Character array :"+ Arrays.toString(chArray)); }} |
Output: convert String to char & character array in java
Input String : JavaChar at zero index : JChar at 1 index : aChar at 2 index : vChar at 3 index : aPrint all characters using loop : JavaString to Character array :[J, a, v, a] |
