Conversion between character and int in Java

Question

You cannot convert from int to char, so this would be illegal int i = 88; char c = i;,

However this is allowed char c = 88;.

Isn\'t

Answer 1

Its because the literals for integer or smaller than int as byte ,short and char is int. Understand the following in this way.

code:

  byte a = 10;//compile fine
  byte b= 11;//compile fine
  byte c = a+b;//compiler error[says that result of **a+b** is **int**]

the same happens for any mathematical operations as of 'Divide', 'multiply', and other arithmetic operation. so cast the result to get the literal in desired data type

byte c = (byte)(a+b);

So that the same reason why the value int need to have primitive cast to change the value in char. Hope this make some sense.
