Question

How can I convert a long to int in Java?

Answer 1

Updated, in Java 8:

Math.toIntExact(value); 

Original Answer:

Simple type casting should do it:

long l = 100000; int i = (int) l; 

Note, however, that large numbers (usually larger than 2147483647 and smaller than -2147483648) will lose some of the bits and would be represented incorrectly.

For instance, 2147483648 would be represented as -2147483648.

Answer 2

Long x = 100L; int y = x.intValue();
