Hi Friend,

Try this:

import javax.swing.*;
import java.io.*;
class CreateTable{
    public static void main(String[] args)throws Exception{
      BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
      StringBuffer buffer=new StringBuffer();
      System.out.println("Enter number: ");
      String st=br.readLine();
      int n=Integer.parseInt(st);
int result;
for (int a = 1; a <= 10; a++)
{
result = n * a;
buffer.append(n);
buffer.append(" * ");
buffer.append(a);
buffer.append(" = ");
buffer.append(result);
buffer.append("\n");
}
JOptionPane.showMessageDialog(null,buffer.toString());
}
}

Thanks
