Automatically Convert C# Unsigned Integer Types to java using CodePorting Engine

Question

We have shown you in previous blog posts that how developers can translate C# properties to java using CodePorting C#2Java App.  CodePorting is determined to translate those C# language constructs to java code which are not available in java and this will be achieved by CodePorting C#2Java intelligent engine. Unsigned and signed data types contains same amount of memory in C#.  C# provides eight predefined signed and unsigned integer types whereas Java has four signed integer types and no unsigned ones.

See following table:

C# Type	Description	Java Equivalent
sbyte	Signed 8-bit	byte
short	Signed 16-bit	short
int	Signed 32-bit	int
long	Signed 64-bit	long
byte	Unsigned 8-bit	n/a
ushort	Unsigned 16-bit	n/a
uint	Unsigned 32-bit	n/a
ulong	Unsigned 64-bit	n/a

 

CodePorting C#2Java automatically converts C#'s unsigned integer types to higher signed types.  This eliminates the chances of data loss in arithmetic operations.

 

Following example converts C# unsigned integer type to java:

 

C# Code:

 

namespace C#2Java.Samples.Convert.UnsignedArithmetic.UInt

{

    public class UnsignedArithematic

    {

        void Method(long l, uint u)

        {

            l = MethodReturnsUInt();

            l = u + MethodReturnsUInt();

            u = MethodReturnsUInt();

            l = MethodReturnsUIntArray()[0];

        }

        uint MethodReturnsUInt()

        {

            return 42;

        }

        uint[] MethodReturnsUIntArray()

        {

            uint[] uints = { 42, 127, 155 };

            return uints;

        }

    }

}

 

Java Code Generated by CodePorting:

 

package C#2Java.Samples.Convert.UnsignedArithmetic.UInt;

// ********* THIS FILE IS AUTO PORTED FORM C# USING CODEPORTING.COM *********

public class UnsignedArithematic

{

    private void method(long l, /*uint*/long u)

    {

        l = (methodReturnsUInt() & 0xFFFFFFFFL);

        l = (u & 0xFFFFFFFFL) + (methodReturnsUInt() & 0xFFFFFFFFL);

        u = methodReturnsUInt();

        l = (methodReturnsUIntArray()[0] & 0xFFFFFFFFL);

    }

    private /*uint*/long methodReturnsUInt()

    {

        return 42;

    }

    private /*uint*/long[] methodReturnsUIntArray()

    {

        /*uint*/long[] uints = { 42, 127, 155 };

        return uints;

    }

}

 

It is clear for the above example that CodePorting C#2Java engine intelligently converts the C# unsigned data types to higher signs in java codes to avoid any data loss accuracy.

Overview:   CodePorting C#2Java App

 

CodePorting helps you make your .NET applications cross platform compatible and allows migrating your .NET solutions, projects and files into Java in the cloud. Other than speed and accuracy of conversion; port your C# code directly either by uploading .cs files contained in a .zip file or import directly from popular version control repositories like GIT, Mercurial HG and SubVersion. You can also download a Microsoft Visual Studio plugin and convert C# code in the real time without leaving the development environment. You may also build your own customized code conversion applications using CodePorting APIs.
