Assigning a value to long data type in java - defaulting to int

Question

long val = 5000000000;

The error during this assignment is:

The literal 5000000000 of type int is out of range

Why does the compiler by default assume the literal to be type int when it is declared with type long?

Answer 1

You can use:

long val = 5000000000L;

Answer 2

There is aspecific suffixes for long i.e L. If there is no suffix, then 5000000000 assumed to be an int type. And 5000000000 is out of int range, causing the erro. So you need to add L at the end of 5000000000 for it to be treated as a long value. Change your declaration from

long val = 5000000000;

to

long val = 5000000000L;
