Overview
Character information is maintained in Java by the primitive type char, which was designed based on the original Unicode 1.0 specification that allowed only 216 code points, so it was defined as a fixed-with 16-bit/2-byte entity. Since then, the Unicode standard has evolved to allow for characters whose representation requires more than 16 bits.
U+n Notation Support
U+n notation is supported in Java as follows:
