Question

incompatible types: possible lossy conversion from int to char in java.how to solve it.

Answer 1

This problem occurs as int is 4 byte and char is 2 byte. So you have to type cast explicitly to avoid error.

e.g:==  int a=10;

            char c=(char)a;

Answer 2

Lossy conversion means you are losing some information.

if int is 4 bytes and char is 2 bytes how can you stored 4 byte information in 2 byte.

So if you still want to convert you can explicitly convert by type conversion. But remember you are still losing some information :)
