Parsing string below with regex

I have strings and want to parse.

Examples:

Airtime payment made for UGX5,000 to MTN 077xxxx39
You have received UGX200,000 from 077xxx4515
You have sent UGX1,033,000 to 078xxx3370

In the above case, i want to parse the money string and the telephone number string. I thought of using split, but the strings not the same numbers.

Another type that I want to parse.

Your balance is UGX200,196

Here can I use split and get the last token....

But for the first category, I think that need regex....and I'm not competent with it!

Any one to help me out?

This should work:

    String[] str = new String[]{"Airtime payment made for UGX5,000 to MTN 07745454539", "You have received UGX200,000 from 07744434515", "You have sent UGX1,033,000 to 0744343370", "Your balance is UGX200,196"};
    Pattern p = Pattern.compile("(UGX[0-9,]+)([A-Za-z ]+(\\d+))?");
    for(String s : str)
    {
        Matcher m = p.matcher(s);
        if(m.find())
        {
            if(m.group(3) != null)
            {
                System.out.println("Payment: " + m.group(1));
                System.out.println("Telephone number: " + m.group(3));
            }
            else if(m.group(1) != null)
            {
                System.out.println("Balance: " + m.group(1));
            }
        }
    }

Yields:

Payment: UGX5,000
Telephone number: 07745454539
Payment: UGX200,000
Telephone number: 07744434515
Payment: UGX1,033,000
Telephone number: 0744343370
Balance: UGX200,196
