Convert C# Using Statement To Java Online using CodePorting C# to Java App

C# use using Statement to define its scope outside of which an object or objects are disposed. But there is no equivalent syntax statement in Java. CodePorting C#2Java engine intelligently translates the C# code and handle this situation by producing try/catch block in java code. This Technique converts C# code to java code with same formatting ready to be complied.

Following example shows migration of C# using statement in java:

[B]C# Code:[/B]


using System.IO;namespace CsPorter.Tests.Convert.LanguageConstructs.UsingStatement
{
    [B]public[/B] [B]class[/B] Test2
    {
        [B]void[/B] Method()
        {
 
            [I]//some comments (vertical indent)[/I]
            using (Stream stream = [B]new[/B] FileStream("nowhere", FileMode.Open))
            {
                stream.ReadByte();
            }
 
                [I]//horisontal indent[/I]
                using (Stream stream = [B]new[/B] FileStream("nowhere", FileMode.Open))
                {
                    stream.ReadByte();
                }
        }
    }
} 
 
[B]Java code generated by CodePorting:[/B]

    {
 
        [I]//some comments (vertical indent)[/I]
        Stream stream = [B]new[/B] FileStream("nowhere", FileMode.OPEN);
        [B]try[/B] [I]/*JAVA: was using*/[/I]
        {
            stream.readByte();
        }
        [B]finally[/B] { [B]if[/B] (stream != [B]null[/B]) stream.close(); }
 
            [I]//horisontal indent[/I]
            Stream stream1 = [B]new[/B] FileStream("nowhere", FileMode.OPEN);
            [B]try[/B] [I]/*JAVA: was using*/[/I]
            {
                stream1.readByte();
            }
            [B]finally[/B] { [B]if[/B] (stream1 != [B]null[/B]) stream1.close(); }
    }
}

Code (markup):

It is clear from above example that CodePorting C#2Java engine automatically generated the try/catch code to handle the using statement.
