Unicode was originally designed as a fixed-width 16-bit character encoding. The primitive data type char in the Java programming language was intended to take advantage of this design by providing a simple data type that could hold any character. However, it turned out that the 65,536 ...
The Java programming language provides a wrapper class that "wraps" the char in a Character object for this purpose. An object of type Character contains a single field, whose type is char. This Character class also offers a number of useful class (that is, static) methods for manipulating ...
Most of the time, if you are using a single character value, you will use the primitive char type. There are times, however, when you need to use a char as an object—for example, as a method argument where an object is expected. The Java programming language provides a wrapper class...

Other Primitive Generators Byte Generator: This generator creates byte arrays with lengths biased or uniformly distributed within specified ranges. Gen<byte[]> gen = BytesGen.biased(int minLength, int maxLength); Gen<byte[]> gen = BytesGen.arbitrary(int minLength, int maxLength); Character Genera...
Else it trims any character specified in the second parameter. true Always returns a true value. Use the function syntax(true()) if there's a column named 'true'. typeMatch Matches the type of the column. Can only be used in pattern expressions.number matches short, integer, long, ...
can be encapsulated inside library-supplied objects if required. The Java programming language follows C and C++ fairly closely in its set of basic data types, with a couple of minor exceptions. There are only three groups of primitive data types, namely,numerictypes,charactertypes, andBoolean...
