        double d = 543.48;
        String s = Double.toString(d);
        System.out.println("s = "+s);

        int dot = s.indexOf('.');

        System.out
                .println(dot + " digits " + "before decimal point.");
        System.out.println((s.length() - dot - 1)
                + " digits after decimal point.");
        
        int i = 190;
        String s3 = Integer.toString(i); 
        System.out.println("s3 = "+s3);

    }
}

Output

s = 543.48
3 digits before decimal point.
2 digits after decimal point.
s3 = 190
