Question

Answer 1

You can use BigDecimal, if you want the exact value that you have in Excel Sheet: -

BigDecimal bd = new BigDecimal("4256411411");
System.out.println(bd.doubleValue());

// If you are sure that's not a floating point number, then use
System.out.println(bd.longValue());  

Prints: -

4.256411411E9  
4256411411
