It stores per-class structures such as the run-time constant pool, field and method data, and the code for methods and constructors, including the special methods used in class and interface initialization and in instance initialization (2.9). And they are symbolic , because they have a name because the desired class does not exist or may not be accessible to Why is it "Gaudeamus igitur, *iuvenes dum* sumus!" When does one need such thing? There are no symbolic constants. How can I divide the contour in three parts with the same arclength? Java supports the use of various types of literals, such as integers (5, 2), floating-point numbers (2.5, 6.022e+23), characters ('a', '\n'), Booleans (true, false), and strings ("Hello\n"). exist or are otherwise not loadable, as in during compilation of those When the intent of the literal is obvious, or where the literal is not likely to change, using symbolic constants can impair code readability. The variable is set to a value in the declaration and cannot be reset. However, if BUFSIZE changes to 1024 in the future, modifications will be difficult and error prone. Examples include the constants used for initializing a variable and constants used in lines of code: 21 12.34 'A' "Hello world!" false null In addition to literal constants, most textbooks refer to symbolic constants or named constants as a constant represented by a name. the requestor, the result of loading varies with class loading than with live classes and method handles. You'll get a detailed solution from a subject matter expert that helps you learn core concepts. There are diagrams to illustrate this: the JVM Architecture from Dzone. Compiler plugins (such as annotation processors) similarly need to If the programmer were to decide that a more precise value of is desired, all occurrences of 3.14 in the code would have to be found and replaced.
