Difference between C# and Java

C# and Java are comparative languages that are written statically, firmly, and plainly. Both are class-based, object- oriented and composed with semi-interpretation, both utilize rubbish gathering, 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.


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.

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 prehistoric 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 it may, 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.


From the above article we can conclude that Java did not support unsigned integers whereas C# supports unsigned integers.
