Generate Special character

[daina]

Hi

can anybody tell me how to generate all the special characters randomly.

Try to randomly get the numbers and print their ascii characters. It is very easy to do.

There is a method called random in Math. java.Math.random(). See javadocs.

Thanks

Use the following program

Sample output:

import java.util.Random;

public class SpecialChars
{
	static int start[] = {
		0, 91, 123
	};
	static int end[] = {
		64, 96, 255
	};
	
	static String special = null;
	
	static Random random = new Random();
	
	public SpecialChars()
	{
		if( special == null )
		{
			init();
		}
	}
	
	private void init()
	{
		special = "";
		for( int count = 0; count < start.length; count++ )
		{
			int _start = start[ count ];
			int _end = end[ count ];
			
			for( int loop = _start; loop <= _end; loop++ )
			{
				special += (char)loop;
			}
		}
	}
	
	private char getRandom()
	{
		int rand = Math.abs(random.nextInt() % special.length() );
		return special.charAt( rand );
	}
	
	public static void main( String s[] )
	{
		SpecialChars sp = new SpecialChars();
		
		for( int count = 0; count < 10; count++ )
		{
			System.out.println( sp.getRandom() );
		}
	}
}

sorry, it is very complex code for small thing .Try the below code. It will definetely work. I have not used random. But you have character only from 0 to 255 and so try to generate numbers between it and print the character.

1 import java.io.*;$
2 class Ascii {$
3 public static void main(String args[]) {$
4 System.out.println("Hai");$
5 for (int i=0;i<255;i++) {$
6 System.out.print((char)i);$
7 }$
8 }$
9 }$

If a code is longer in lines of code, it doesn't mean, it is complex. Daina wants to print special characters randomly. Above code, which simply prints all the first 255 chars will also print alphabets.

Sorry mohit, If i have hurt you feelings. I don't think daina knows java very well or else she would not have asked simple question. So you should have given the program in a more simple way so that she can understand it. When I meant complex, I mean for a person who is new will be afraid of it, But I accept it is the correct method of doing.

Once again I apologise, If i have hurt you
