Highlight the difference between C Sharp and Java .

C# and Java are both new-generation languages descended from a line including C and C++. Each includes advanced features, like garbage collection, which remove some of the low level maintenance tasks from the programmer. In a lot of areas they are syntactically similar.

Both C# and Java compile initially to an intermediate language: C# to Microsoft Intermediate Language (MSIL), and Java to Java bytecode. In each case the intermediate language can be run - by interpretation or just-in-time compilation on an appropriate 'virtual machine'. In C#, however, more support is given for the further compilation of the intermediate language code into native code.

C# contains more primitive data types than Java, and also allows more extension to the value types. For example, C# supports 'enumerations', type-safe value types which are limited to a defined set of constant variables, and 'structs', which are user-defined value types.

Unlike Java, C# has the useful feature that we can overload various operators.

Like Java, C# gives up on multiple class inheritance in favour of a single inheritance model extended by the multiple inheritances of interfaces. However, polymorphism is handled in a more complicated fashion; with derived class methods either 'overriding' or 'hiding' super class methods

C# also uses 'delegates'-type-safe method pointers. These are used to implement event handling.

In Java, multi-dimensional arrays are implemented solely with single-dimensional arrays (Where arrays can be members of other arrays). In addition to jagged arrays, however, C# also implements genuine rectangular arrays.
