we can consider using a biginteger . it operates on arbitrary precision integers and can, therefore, be used in myriad contexts. here’s how we can convert a hex string to a biginteger and then extract the integer value: @
StringstringObject="123.45";BigDecimalbigDecimalObject=newBigDecimal(stringObject);System.out.println(bigDecimalObject); and output: Exceptionin thread"main"java.lang.NumberFormatException The fix is that BigDecimal will convert the string which contains numbers only. Try to avoid the String with non-num...
