Encryption and Decryption

[padmanabhanp]

Hai,
I am facing one problem in Encryption(Java). I want to get a string from the user and split that string into characters. After splitting that string into characters, i am changing that character into integer and adding some value to it. what my problem is after adding that value i want change that into String and Store that String in the database.


Thanks in Advance

Hi,

Try this..

int i = 10;
String strTest = Integer.toString(i)
or 
String strTest = "" + i

class encrypt1

public static void main (String args[])
{

String name="welcome";
char ch[]=new char[20];
int j;
char c1;
for(int i=0; i<=name.length()-1; i++)
{
ch[i]=name.charAt(i);
j=ch[i]+5;
c1=(char)j;
System.out.println(c1);
}
}
}

try this code. the changed character is stored in a string.hope it ll be useful. if i havent met ur expectations, pls lemme knw.

public class testSample {

public static void main (String args[])
{
String name="welcome";
String str = "";
char ch[]=new char[name.length()];
char character[]=new char[name.length()];
int j;
char c1;
for(int i=0; i<=name.length()-1; i++)
{
ch[i]=name.charAt(i);
//System.out.println("char is -----"+ch[i]);
j=ch[i]+5;
//System.out.println("j value is ---"+j);
c1=(char)j;
character[i]=c1;
System.out.println("c1 value is---"+c1);
System.out.println("character array----"+character[i]);
}
System.out.println("char array length is---"+ch.length);
int charLength = character.length;
for(int i=0; i<charLength-1;i++){
str= str + character[i];
}
System.out.println("the string is---"+str);
}
}
