Character Array In Java, Char Array Program in Java

Character Array In Java, Char Array Program in Java:-
Char array is used to store char elements using proper sequence, it is basically used in String operation.
Syntax 
char arrayname[] = {'data1', 'data2', 'data3' }
Some Example of Char Array In Java:-
Palindrome Program in Java 
Pallindorm means from left to right and right to left string should be matched.
Pallindorm can be an integer as well as a string.
This program is used to check palindrome using String.
class Checkpallindrom
{
     public static void main(String args[])
     {
          char arr[] = {'m','a','d','a','n'};
          int i,j;
          boolean flag=true;
          for(i=0,j=arr.length-1;i<arr.length/2;i++,j--)
          {
                if(arr[i]!=arr[j])
                {
                    flag=false;
                    System.out.println("Not Pallindrom");
                    break;
                }
          }
         if(flag)
         System.out.println("Pallindrom");
     }
}
This program can be created by String also?
class ArrExample3
{
   public static void main(String args[])
   {
        String arr = "RAMAN";
        int i,j;
        for(i=0,j=arr.length()-1;i<arr.length()/2;i++,j--)
        {
               if(arr.charAt(i)!=arr.charAt(j))
               {
                   System.out.println("Not pallindrom");
                   break;
               }
        } 
        if(i==arr.length()/2)
         System.out.println("Pallindrom");
   }
}
Assignment of  Char Array and String Both?
Q)  WAP to convert Char Array From Upper Case Char to Lower Case Char?
Q)  WAP to find kth max char and kth min char?
Q)  WAP to count total numeric, alphabets, and special char in Char Array?
Q)  WAP to sort the char Array in descending order?
Q) WAP to convert char array to integer array?

    Pallindrom program without using third variable?

    import java.util.Scanner;
    class Pallindrom
    {

    public static void main(String args[])
    {
    // char arr[] = {'d','a','m','a','n'};
    int i,j;
    Scanner sc= new Scanner(System.in);
    System.out.println("Enter size of char array");
    char arr[] = new char[sc.nextInt()] ;
    for(i=0;i 'A'

    }
    for(i=0,j=arr.length-1 ; i<arr.length/2; i++,j--)
    {
    if(arr[i]!=arr[j])
    {
    System.out.println("NOT Pallindrom");
    break;
    }


    }
    if(i==arr.length/2)
    System.out.println("Pallindrom");

    }


    }

Uncontrolled form input in React-JS

  Uncontrolled form input in React-JS? If we want to take input from users without any separate event handling then we can uncontrolled the data binding technique. The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
