Likewise, the default values for float and double end with f and d, respectively. It is important to define each variable using the appropriate data type. In fact, limiting the range of a variable can serve as very useful documentation to better understand its meaning during code inspection and/or maintenance. Furthermore, it can also help save memory if a variable is defined as byte instead of int (since byte is four times smaller than int). Literals A literal is a value assigned to a variable of a specific type.
Floating point literals can also be expressed in scientific notation using E or e. org for more details). An example of this is as follows: char char char char gbPoundUniSymbol = '\u00A3'; gbPoundSymbol = '£'; dollarUniSymbol = '\u0024'; dollarSymbol = '$'; Java Data Types ❘ 29 There are also some characters, called escape characters, that have a special meaning. They are used for displaying text in specific ways, either for inserting tabs or enters where desired, or by displaying a character that’s normally reserved for code syntax.
Many of the concepts that are introduced here will be elaborated on in later chapters. A Short Java History In 1991, Sun Microsystems funded the research project called “Green” to design a programming language to be used in intelligent consumer electronic devices, like televisions, VCRs, and washing machines. Since home appliance processor chips change on a continuous basis, the programming language used needed to be extremely portable. Existing programming languages such as C++ were clearly not suitable.
