Java Program On ASCII Code And Equivalent Character

Input an ASCII code, reverse the ASCII code and display the equivalent character

e.g: Entered value: 98

Reverse: 89

Output: Y

 

import java.util.*;

class Char5

{

 Int n, rev=0;

Scanner sc=new Scanner(System.in);

void take()

{

System.out.print(“\nEnter the ASCII Code:”);

n=sc.nextInt();

if(n%10==0)

{

 System.out.print(“\n Reversing not possible.”);

System.exit(0);

}

while(n>0)

{

 rev=rev*10+n%10;

n=n/10;

}

System.out.print((char)rev);

}

public static void main(String args[])

{

Char5 ob=new Char5 ();

ob.take ();

}

}

Java Program On Displaying Character Corresponding To Number

Write a program to input a number N (0<N<27). Display the letter corresponding to the number (if N is 1, display A)

 

import java.util.*;

class Char4

{

 char ch;

int N;

void take()

{

for(;; )

{

System.out.print(“\nEnter the number (1-26):”);

N=sc.nextInt();

If(N>0 && N<27)

break;

}

System.out.print((char)(N+64));

}

public static void main(String args[])

{

Char4 ob=new Char4();

ob.take ();

}

 

}

Java Program To Display All Alternate Characters From A to Z

class Char3

{

 char ch;

int i;

void take()

{

 for(i=65;i<=90;i=i+2)

{

ch=(char)(i);

System.out.print(“ “+ch);

}

public static void main(String args[])

{

Char3 ob=new Char3();

ob.take ();

}

}

Enter a character and display the next 5 characters Using Java

import java.util.*;

class Char2

{

 char ch;

int i;

Scanner sc=new Scanner(System.in);

void take()

{

 System.out.print(“\nEnter any character:”);

ch=sc.next().charAt(0);//A

ch=(char)(ch+1);//B

for(i=0;i<5;i++)

{

System.out.print(“ “+ch);//B C

ch=(char)(ch+1);

}

public static void main(String args[])

{

Char2 ob=new Char2();

ob.take ();

}

 }

Java Program on Displaying 10th Character from Entered Character

Enter a character and display the next 10^th character in ASCII table

import java.util.*;

class Char1

{

 char ch;

int i;

Scanner sc=new Scanner(System.in);

void take()

{

 System.out.print(“\nEnter any character:”);

ch=sc.next().charAt(0);

i=ch+10;

if(i>90 )

i=65+(i-90);

else if(i>122 )

i=97+(i-122);

ch=(char)i;

System.out.println(“\n10th character=”+ch);

}

public static void main(String args[])

{

Char1 ob=new Char1();

ob.show();

}

}
