how to extract numeric values from input string in java

Question

How can I extract only the numeric values from the input string?

For example, the input string may be like this:

String str=\"abc d 1234567890pqr 548         


        

Answer 1

 public static String convertBudgetStringToPriceInteger(String budget) {
    if (!AndroidUtils.isEmpty(budget) && !"0".equalsIgnoreCase(budget)) {
        double numbers = getNumericFromString(budget);
        if( budget.contains("Crore") ){
            numbers= numbers* 10000000;
        }else if(budget.contains("Lac")){
            numbers= numbers* 100000;
        }
        return removeTrailingZeroesFromDouble(numbers);
    }else{
        return "0";
    }
}

Get numeric value from alphanumeric string

 public static double getNumericFromString(String string){
    try {
        if(!AndroidUtils.isEmpty(string)){
            String commaRemovedString = string.replaceAll(",","");
            return Double.parseDouble(commaRemovedString.replaceAll("[A-z]+$", ""));
            /*return Double.parseDouble(string.replaceAll("[^[0-9]+[.[0-9]]*]", "").trim());*/

        }
    }catch (NumberFormatException e){
        e.printStackTrace();
    }
    return 0;
}

For eg . If i pass 1.5 lac or 15,0000 or 15 Crores then we can get numeric value from these fucntion . We can customize string according to our needs. For eg. Result would be 150000 in case of 1.5 Lac
