How to Convert/Parse from String to Char in Java?

You can use the .charAt(int) function with Strings to retrieve the char value at any index. If you want to convert the String to a char array, try calling .toCharArray() on the String.

String g = "line";
char c = g.charAt(0);  // returns 'l'
char[] c_arr = g.toCharArray(); // returns a length 4 char array ['l','i','n','e']

you can use this trick :

String s = "p";

char c = s.charAt(0);

I found this useful:

double  --> Double.parseDouble(String);
float   --> Float.parseFloat(String);
long    --> Long.parseLong(String);
int     --> Integer.parseInt(String);
char    --> stringGoesHere.charAt(int position);
short   --> Short.parseShort(String);
byte    --> Byte.parseByte(String);
boolean --> Boolean.parseBoolean(String);

If the string is 1 character long, just take that character. If the string is not 1 character long, it cannot be parsed into a character.

 String string = "This is Yasir Shabbir ";
 for(char ch : string.toCharArray()){

 }

or If you want individually then you can as

char ch = string.charAt(1);

org.apache.commons.lang.StringEscapeUtils.(un)EscapeJava methods are probaby what you want

Answer from brainzzy not mine :

The simplest way to convert a String to a char is using charAt():

String stringAns="hello";
char charAns=stringAns.charAt(0);//Gives You 'h'
char charAns=stringAns.charAt(1);//Gives You 'e'
char charAns=stringAns.charAt(2);//Gives You 'l'
char charAns=stringAns.charAt(3);//Gives You 'l'
char charAns=stringAns.charAt(4);//Gives You 'o'
char charAns=stringAns.charAt(5);//Gives You:: Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String index out of range: 5

Here is a full script:

import java.util.Scanner;

class demo {
    String accNo,name,fatherName,motherName;
    int age;
    static double rate=0.25;
    static double balance=1000;
    Scanner scanString=new Scanner(System.in);
    Scanner scanNum=new Scanner(System.in);

    void input()
    {
        System.out.print("Account Number:");
        accNo=scanString.nextLine();
        System.out.print("Name:");
        name=scanString.nextLine();
        System.out.print("Father's Name:");
        fatherName=scanString.nextLine();
        System.out.print("Mother's Name:");
        motherName=scanString.nextLine();
        System.out.print("Age:");
        age=scanNum.nextInt();
        System.out.println();
    }

    void withdraw() {
        System.out.print("How Much:");
        double withdraw=scanNum.nextDouble();
        balance=balance-withdraw;
        if(balance<1000)
        {
            System.out.println("Invalid Data Entry\n Balance below Rs 1000 not allowed");
            System.exit(0);
        }       
    }

    void deposit() {
        System.out.print("How Much:");
        double deposit=scanNum.nextDouble();
        balance=balance+deposit;
    }

    void display() {
        System.out.println("Your  Balnce:Rs "+balance);
    }

    void oneYear() {
        System.out.println("After one year:");
        balance+=balance*rate*0.01;
    }

    public static void main(String args[]) {
        demo d1=new demo();
        d1.input();
        d1.display();
        while(true) {//Withdraw/Deposit
            System.out.println("Withdraw/Deposit Press W/D:");
            String reply1= ((d1.scanString.nextLine()).toLowerCase()).trim();
            char reply=reply1.charAt(0);
            if(reply=='w') {
                d1.withdraw();
            }
            else if(reply=='d') {
                d1.deposit();
            }
            else {
                System.out.println("Invalid Entry");
            }
            //More Manipulation 
            System.out.println("Want More Manipulations: Y/N:");
            String manipulation1= ((d1.scanString.nextLine()).toLowerCase()).trim();

            char manipulation=manipulation1.charAt(0);
            System.out.println(manipulation);

            if(manipulation=='y') { }
            else if(manipulation=='n') {
                break;
            }
            else {
                System.out.println("Invalid Entry");
                break;
            }
        }   

        d1.oneYear();
        d1.display();   
    }
}

If you want to parse a String to a char, whereas the String object represent more than one character, you just simply use the following expression: char c = (char) Integer.parseInt(s). Where s equals the String you want to parse. Most people forget that char's represent a 16-bit number, and thus can be a part of any numerical expression :)

import java.io.*;
class ss1 
{
    public static void main(String args[]) 
    {
        String a = new String("sample");
        System.out.println("Result: ");
        for(int i=0;i<a.length();i++)
        {
            System.out.println(a.charAt(i));
        }
    }
}

You can do the following:

String str = "abcd";
char arr[] = new char[len]; // len is the length of the array
arr = str.toCharArray();

You can simply use the toCharArray() to convert a string to char array:

    Scanner s=new Scanner(System.in);
    System.out.print("Enter some String:");
    String str=s.nextLine();
    char a[]=str.toCharArray();

An Essay way :

public class CharToInt{  
public static void main(String[] poo){  
String ss="toyota";
for(int i=0;i<ss.length();i++)
  {
     char c = ss.charAt(i); 
    // int a=c;  
     System.out.println(c); } } 
}

You can use the .charAt(int) function with Strings to retrieve the char value at any index. If you want to convert the String to a char array, try calling .toCharArray() on the String. If the string is 1 character long, just take that character by calling .charAt(0) (or .First() in C#).
