The cytoplasm is about 80% water and usually colorless. It is within the cytoplasm that most cellular activities occur, such as many metabolic pathways including glycolysis, and processes such as cell division.he physical properties of the cytoplasm have been contested in recent years. It remains uncertain how the varied components of the cytoplasm interact to allow movement of particles and organelles while maintaining the cellâs structure.
There are times, however, when you need to use a char as an objectâfor example, as a method argument where an object is expected. 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 (i.e., static) methods for manipulating characters.
Java was created around the time when the Unicode standard had values defined for a much smaller set of characters. Back then it was felt that 16-bits would be more than enough to encode all the characters that would ever be needed. With that in mind Java was designed to use UTF-16. In fact, the char data type was originally used to be able to represent a 16-bit Unicode code point. Since Java SE v5.0, the char now represents a code unit. It makes little difference for representing characters that are in the basic multilingual plane because the value of the code unit is the same as the code point.
