SOME VERY SIMPLE AND BASIC JAVA SOURCE CODES THAT I DEVELOPED. FEEL FREE TO POINT OUT ERRORS IF ANY.(PART-3)

SOURCE CODE #8
//A Simple java program to find the number of characters present in a String.
import java.util.*;
import java.io.*;
public class NumberOfCharactersInAString
{
public static void main(String args[]) throws IOException
{
int chara;
System.out.println("Enter a String");
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String str = br.readLine();
for(chara=0; chara {}
System.out.println("The total number of characters present in the String is " + chara);
}

}

OUTPUT FOR SOURCE CODE #8

Enter a String

Hemapriyagopal

The total number of characters present in the String is 14

SOURCE CODE #9

//How to input a string from the monitor and print the reverse of the string on the screen

import java.io.*;

public class StringReverse {

public static void main(String args[]) throws IOException

{

String name;

String revname;

System.out.println("Enter a string");

BufferedReader br = new BufferedReader (new InputStreamReader(System.in));

name = br.readLine();

revname = new StringBuilder(name).reverse().toString();

System.out.println("The reversed string is " + revname);

}

}

OUTPUT FOR SOURCE CODE #9

Enter a string

Hemapriyagopal

The reversed string is lapogayirpameH

OUTPUT-2

as df

The reversed string is fd sa
