Webchar: The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65,535 inclusive). In addition to the eight primitive data types listed above, the Java programming language also provides special support for character strings via the java.lang.String class. WebThese type aliases are equivalent to using the name of the corresponding base type in the previous table and are appropriately defined for each data model. For example, the type name uint8_t is an alias for the type unsigned char.
