Advantages and Disadvantages of .NET and Java

Net application development allows you to implement many effective commercial ideas and approaches. Comfort means different things to different people. Someone is comfortable with what he is used to. Someone needs auto-checking of classes, and for the third, speed is most important. While any parameter can be important for programmers, for clients the goal is the same – it is a smoothly running efficient application. Let’s compare two popular languages ​​and development platforms.

. NET advantages

Benefits of . NET overlap with Java in some aspects. Here are some indicators that are roughly equal. The preferences of different developers are purely individual:

  1. Integration. With Sharpe, everything is simple – installed Visual Studio and no problems, there is both the .NET Framework included and the SDK. For Java, you need to install the runtime environment, called on the Oracle website simply “Java”, then the JDK, then the IDE, and Oracle does not offer it, you need to look elsewhere, and also make sure that the versions are the same in all three products. The second approach is a little more complicated. But, in general, this slows down the process only at the very beginning and insignificantly.
  2. Cross-platform is an attribute of both languages. It used to be a Java privilege. But with the advent of .NET Core, this platform also runs on different operating systems.
  3. Speed. There is also no single answer to this point. The question is: what is more important to you – to write the code quickly and test it slowly, or vice versa? In Java, the writing process takes longer, but testing and debugging will take less time. The choice depends on the exit criteria for the project.

Compared to the .NET platform, Java still has disadvantages:

  • Java requires immeasurably more memory consumption due to the fact that it does not have collections of primitive types. For example, a list of 100 million bytes in C # is about 100 million bytes and will take (plus overhead information – several tens of bytes), and in Java – 2.1 billion bytes (since an object wrapper must be created over each byte).
  • The lack of unsigned integer types in Java.
  • Lack of compile-time constants, which are replaced by their own text at runtime. There is a mix of static and final modifiers that have the same effect as a constant, but these constants are not expanded at compile time.
  • Lack of properties and especially indexers. Perhaps this is not a serious drawback, but for some, especially young programmers, it interferes. Use instead of list [i] = 100; cumbersome and unobvious construction list.set (i, 100); or even worse – list.setElementAt (100, i); the pleasure is not the best.
  • Lack of output parameters for functions.
  • Lack of decimal type. This means that all financial affairs in Java cannot be solved. (There is java.math.BigDecimal, but it is not the same).
  • The impossibility of a variable of an enumerated type with the value of a set of constants. It is possible to make a set of enumerations, but how much resources will it take?
  • No operator overloads.
  • Lack of multidimensional arrays.

Java pros

From the point of view of speed, convenience and quality of development, these bonuses are quite significant:

  1. Most of the external constructs in Java are open source.
  2. It is possible to exit nested loops without using a bad goto statement.
  3. Many people point out that decompilation is much more difficult.
  4. Checked exceptions slow down the process a little, but avoid the inaccuracies of the human factor.
