I am working with an app android studio - mrate is the rate for 1 km distance and replacetext is the distance between two points and replacing the (km) form the distance - when distance value has decimal value (10.5 )then the system is getting an error

String mykm =dbDistance.getText().toString();



String mrate = dbRate.getText().toString();

System.out.println(mrate);



String replacetext;

replacetext = mykm.replace(" km", "");

System.out.println(replacetext);





//convert value into int

int x=Integer.parseInt(mrate);

int y=Integer.parseInt(replacetext);



//sum these two numbers

int z=x+y;



System.out.println(z);

You can also use BigDecimal objects for easy conversion and arithmetics

    BigDecimal decimal1 = new BigDecimal("1.024");

    BigDecimal decimal2 = new BigDecimal("52.232");

    BigDecimal decimal3 = decimal1.add(decimal2);

    BigDecimal decimal4 = decimal3.multiply(decimal1);

    String newValue = decimal4.toString();

BigDecimal is very powerful especially if you want precision with large decimal places or large numbers in general

//convert value into int

int x=Integer.parseInt(mrate);

int y=Integer.parseInt(replacetext);

If you've got decimal values, use Double or Float instead of Integer
