How to remove comma or unwanted characters from a string?

Question

I want to know how I can remove comma or another characters from a string, like 

I have string1 which is Rs. 30,000 and strng2 which is 30000 and these strings values are coming dynamically.

Now I have to compare them and using this code

string1 which is Rs. 30,000 and strng2 which is 30000

 

if(string1.contains(string2)){

Sysyem.out.println("true");

}

but because of "Rs." and "," result is not coming true, Can you help me how can I remove Rs. and comma from the strings?

Thanks For help!

Answer 1

class Removal

{

public static void main(String args[])

{

String str1=new String("Rs. 30,000");

String str2=new String("30000");

String string1="";

//lets us first remove irrelevant data from str1

int ch;    // This is used to typecast the character to integer value(ASCII value of a character). 

for(int i=0;i<str1.length();i++)

{

ch=(int)str1.charAt(i);

if(ch<=57 && ch>=48)   // 0 is represented as 48    and    9 is represented as 57 in ASCII

{

string1=string1+str1.charAt(i);   // concatenation of number

}

}

 

// our final aim to compare 

if(string1.equals(str2))

System.out.println("True");

else

System.out.println("False");

}

}

Answer 2

This is another way to remove comma or other part of string:

you have  String str1=new String("Rs. 30,000");

              String str2=new String("30000");

              str1= str1.replace(",", "");

              str1= str1.replace("Rs.", "");

So now if you compare them so result will be true.

                  if(string1.equals(string2)){

                   Sysyem.out.println("true");

                   }

I hope you like it !

Thanks @jatin but in this case if another new character comes again in string so i need to change in code So i think Answer given by @Tiger98 above will be fit for this situation, i appreciate your effort.
