Difference between C# and Java
Java and C# are the most popularly used programs nowadays. Java which was developed earlier than C#, has developed a big and dynamic user base. Since then, it has become the most used program in a lot of current computer science courses, especially in areas where networking is involved. C# on the other hand, is a younger language than Java. Its developer, Microsoft, has made a thorough research about older languages like Java and Object Pascal, resolving the problems of run-time environments and its shortcomings. C# has quickly developed into a user-friendly program, incorporating queries which allow users to perform fast data mining and analysis.
Java does not allow pointer arithmetic in their programming language. However, C# allows the use of these pointers and their arithmetic pointers that corresponds it. It has to be noted that these pointers are not recommended for use due to its safety issues. These issues involve the bypassing of the object access' strict rules. In response to the safety threat posed by using pointers, C# has designed code blocks such as the keyword "unsafe" to warn users that the use of these codes are not as safe as other codes. To disable this code, the word /unsafe is incorporated in the database structure.
Using the "struct" keyword, the C# program allows the user to make value types that are user-based. These values types are perceived by programmers as lightweight classes. These value types are accepted as values instead of references. These structs has a number of restrictions. Because structs have no "null" values, the default for blank columns are filled with the number zero. Only with arguments can the programmer label supplementary constructors. Conclusively, structs do not have virtual method tables which make it incapable of inheritance, but can put into operation interfaces. On the other hand, because of the value type's intricacies, Java does not include this in their software.
Enumerations in Java are derived from objects. In Java, the only enumerations that are considered valid are the ones that are programmed in its enumerations. In Java, these enumerations have their own fields which are modifiable. The "enum" constants - the pre-described number of instances, are allowed as classes in Java. On the other hand, enumerations in C# are based on predated integer type 8-bit, 16-bit, 32-bit and 64-bit types. An open cast may be required to assign a value of these primitive types in order for it to be a legitimate value of enumeration type. Enumerations in both C# and Java are convertible to strings and can also be incorporated into switch statements.
Similarities and Differences
- Java is an older software program developed by Sun Microsystems which has evolved to become more usable in programming languages.
- C# is a newer version of software programs developed by Microsoft, which aims in giving the programmers the ability to make user-defined programs and languages.
- Java does not include value types and pointers in their program.
- C# is more dynamic and user-friendly and has solved the long standing problems of runtime environments.
