How to convert string to long [duplicate]

Question

how do you convert a string into a long.

for int you

int i = 3423; String str; str = str.valueOf(i); 

so how do you go the other way but with long.

long lg; String Str = "1333073704000" lg = lg.valueOf(Str); 

Answer 1

This is a common way to do it:

long l = Long.parseLong(str); 

There is also this method: Long.valueOf(str); Difference is that parseLong returns a primitive long while valueOf returns a new Long() object.

Answer 2

The method for converting a string to a long is Long.parseLong. Modifying your example:

String s = "1333073704000"; long l = Long.parseLong(s); // Now l = 1333073704000
