Difference between C# and Java

These languages are programming languages and both are machine languages which are easily understood by the human. C# and Java are comparative languages that are written statically, firmly, and with effort. Both are class-based, object- oriented and composed with semi-interpretation, both utilize garbage collecting, and both belongs to curly brace languages, similar to C and C++.


C# is a multi-worldview programming language incorporating strong writing, basic, explanatory, practical, nonexclusive, class-based, and segment situated programming disciplines. It was produced by Microsoft. And it is used for developing desktop applications.


Java is a universally useful PC programming language that is simultaneous, class based, protest oriented, and particularly intended to have as few execution conditions as would be prudent. And it is also used for developing mobile application.

C# VS Java

This article looks at above given programming languages. While the focal point of this article is primarily their features of libraries and platforms.

  • Type system:

C# usually has its unified type system in which numerous kinds at last get from a typical root sort. Thus, different types actualize the strategies for this root sort.

In Java, the primitive types are extraordinary in a way that they are not based on object oriented and they were not characterized utilizing the language itself. They likewise don’t impart a typical precursor to reference sorts. The Java reference sorts all get from a typical root sort.

  • Integers:

C# underpins unsigned notwithstanding the types of signed integers. The unsigned sorts are byte, uint ushort and ulong for 8, 32, 16 and 64 bit widths, separately

Java does not highlight type of unsigned integers. Specifically, Java does not have a primitive sort for an unsigned byte. Rather, Java’s byte sort is sign augmented, which is a typical foundation of confusion and bugs.

  • High-precision:

C# has a sort and exacting documentation for high-accuracy i.e. “28 decimal digits”, decimal math that is suitable for budgetary and money related computations.

Java don’t have such type, the Java library features a discretionary accuracy decimal sort. This is not viewed as a dialect sort and it doesn’t bolster the arithmetic operations; relatively it is a reference sort that must be controlled utilizing the sort strategies.

  • Pointers:

C# allows utilization of pointers and comparing pointer math, the creators of C# had similar worries that pointers could possibly be utilized to sidestep the strict principles for protest get to. In this way, C# as a matter of course additionally blocks pointers.

Java blocks pointers and pointer-math inside the Java runtime environment. The creators of Java language contemplated that pointers usually are one of the fundamental components that empower software engineers to place bugs in their code and picked not to bolster them

  • Compatibility:

Designers of C# have presented a few latest keywords since the main variant. Be that as itmay, rather than characterizing these keywords as worldwide catchphrases, they characterize them as setting delicate keyword.

Designers of Java language have maintained a strategic distance from latest keywords however much as could be expected, inclining toward rather to present new syntactic develops that were not legitimate before or to reuse existing catchphrases in new settings. Along these lines they didn’t risk in reverse compatibility.


C# is used for development of desktop application and the software used for implementing C# is visual studio.

Java has various uses it can be used for developing desktop application along with development of mobile applications. Desktop applications in java are implemented using NetBeans and Eclipse. On the other hand mobile application is developed using Android Studio.



From the above article we can conclude that Java did not support unsigned integers whereas C# supports unsigned integers. But in the present era java has gained much importance as it is used in mobile application development.
