Comparison of C# and Java; ... ^f Same size as double on many implementations. ... fixed size array dynamic size array one-dimensional array
C# provides a built-in decimal type, [95] which has higher precision (but less range) than the Java/C# double. The decimal type is a 128-bit data type suitable for financial and monetary calculations.
Unlike Java, C# additionally supports operator overloading. [ 93 ] Since version 2.0, C# offers parametric polymorphism , i.e. classes with arbitrary or constrained type parameters, e.g. List<T> , a variable-sized array which only can contain elements of type T .

Whether it is a console or a graphical interface application, the program must have an entry point of some sort. The entry point of a C# application is the Main method. There can only be one declaration of this method, and it is a static method in a class. It usually returns void and is passed command-line arguments as an array of strings.
Some array data structures do not reallocate storage, but do store a count of the number of elements of the array in use, called the count or size. This effectively makes the array a dynamic array with a fixed maximum size or capacity; Pascal strings are examples of this.
A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.
