What is the technical name of the syntactic feature “long foo = 12L;” style casting of harded-coded values in Java?
Question
Today, I was trying to cast a hard-coded value into a short and S did not work. So, I went to search for it, but I realized that I do not even know what this feature of Java's syntax is called. Is there a name for it? If not, is there at least a list of all of the possible ways to cast hard-coded numeric values?
Epilouge
After getting the answer "Literals", I was able to answer my question about shorts. In case you are wondering, there is no short literal in Java. You just have to explicitly cast it as so: (short)12
.
Solution
They are called literals.
From the Primitive Data Types page of The Java Tutorials:
A literal is the source code representation of a fixed value; literals are represented directly in your code without requiring computation.
There's a list of literals that can be used in the Primitive Data Types page under the Literals section.
Section 3.10: Literals of the Java Language Specification, Third Edition has a complete list as well.
