How to convert int to byte in Java?

Question

I have this integer in java:

int i = 1067030938;
byte b = (byte) i;

which gives me:

-102

How could I go from b back to i ?

---

I tried :

b = b & 0xff;

but this gives 154

Answer 1

If you have

int i = 1067030938;

And just want the low order 8 bits, then do

i &= 0xff;

System.out.println(i);

Prints

154

If you want the signed value of converted int then do this

i = (byte)i; // will be -102
