I would like to get the unicode character corresponding to the input int

String character = Character.toString( codePoint ) ;

You can assume that input int can be represented as char in java.

No, you cannot assume that.

Most of the over 140,000 characters defined in Unicode , and supported by Java, cannot be represented by the char type. As a 16-bit value, a char is physically incapable.

The char type has been legacy since Java 2, basically broken, with code point support added in Java 5+.
