Is it possible that write a program with Java bytecode instructions directly?
<p>In .NET platform it is possible to write a program with Common Intermediate Language directly and compile the sources with IL Assembler (ILASM).</p>

<p>For example below code is "Hello World" program.</p>

<pre><code>.assembly Hello {}
.assembly extern mscorlib {}
.method static void Main()
{
    .entrypoint
    .maxstack 1
    ldstr "Hello, world!"
    call void [mscorlib]System.Console::WriteLine(string)
    ret
}
</code></pre>

<p>Is it possible that write a program with Java bytecode instructions directly like .NET?</p>
