Statement from text file to code

I was wondering if it is possible to convert conditional statements from a text file straight to code. For example, if in a text file I had:

if(a.getId()==1){System.out.println("YES");}

Is it possible to directly call that into a program, such as this:

for(Node a : nodes){
 >>> The statement from file <<<
}

Hope that makes sense, and thanks in advance. :)

The simplest option would be to use a script engine. Or you can use GroovyShell which is straight forward. Example below.

Binding binding = new Binding();
GroovyShell gShell = new GroovyShell(binding);
Object result= shell.evaluate("int a = 10; a = a + 5; return a");

Not really. Java is compiled, not interpreted. I've seen template engines that generate complete java classes and then compile them into runnable code but it gets pretty hairy pretty quick.
