A Program to check whether String is palindrome or not in Java Language.

//StringPalindromeTest.java
import java.util.Scanner;
public class StringPalindromeTest {
       public static void main(String[] args) {
                  Scanner sc = new Scanner(System.in);
                  String demo = sc.nextLine();
                  if(demo==null){
                         System.out.println("Entered value can't be null.\n");
                  }else{
                         StringBuilder demo2 = new StringBuilder();
                         demo2.append(demo);
                         demo2.reverse();
                         String test = demo2.toString();
                         int b = demo.compareToIgnoreCase(test);
                         if(b==0){
                                System.out.println("Palindrome");
                         }else{
                                System.out.println("Not Palindrome");
                         }
                }
      }
}

Components of C language

Image
There are five main component of C language :- 1. The character set: Any alphabet ,digit or special symbol ,used to represent information is denoted by character. The character in C are grouped into four categories:- i) Letters A...Z and a...z ii) Digits 0,1,2,.....9 iii) Special Symbol ~ ` ! @ # $ % ^ & * () . < > ? / " : ; { }[ ]. iv) White Space,blank space, Carriage return, form feed, newline, horizontal tab. C uses the uppercase letter A to Z, the lowercase letters a to z, the digits 0 to 9, and certain special characters as building blocks to form basic program elements ( e.g., constants, variables, operators, expressions, etc. Some of the special characters are listed below: + - * ~ % / & ( ) { } [ ] ? " < > ! ; : Most versions of the language also allow certain other characters, such as @ and $, to be included within strings and comments. C uses certain combinations of these characters, such as \b,\n and \t, to represent spe...

Decision making using if statement

Image
The if statement is a powerful decision making statement and is used to control the flow of execution of statements. It's a basically two way decision statement and is used in conjuction with an expression. It's syntax is:- "if(test expression)" It allows the computer to evaluate the expression first and then, depending on condition, it transfers the control to a particular statement. This point of program has two paths to follow,one for the true and other for false condition.As shown in figure:-     Practical examples of if statement:- 1. if(bank balance is < 500)     deposit money 2. if(room is dark)     put on lights The if statement may be implemented in different forms depending on the complexity of conditions to be tested. The different forms of if statements are:- 1.Simple if statement 2.if....else statement 3.Nested if....else statement 4. else if ladder 1.Simple if statement.  The general f...

Backslash character constants

Image
Enclosing character constants in single quotes works for most printing characters.A few , however, such as carriage return, can't be. For this reason, C includes special backslash character constants, so that you may easily enter these special characters as constants. You should use the backslash codes instead of their ASCII equivalents to help insure portability. List of backslash character constants are as follows:- Code Meaning \b Backspace \f Form feed \n New line \r Carriage return \t Horizontal tab \" Double quote \' Single quote \\ Backslash \v Vertical tab \a ...
