Java Output Format With Indents As Code:

Question

I generate .java files from a PrintWriter class. These generated files contain many nested for loops. To properly indent everything, I am currently using something like:

for(int j = 0; j < i + 2; j++)
{
    pw.print("    ");
}
pw.println("{");

Just to properly indent the single parentheses.

Obviously, I could just make a method to do this. I'm more wondering if there's a library that will handle indention and such of outputted code.

@Mark Elliot he said Java: I generate .java files from a PrintWriter class. — Nivas

I think you might be better off not doing that in your code ( I dont know of any library that formats PrintWriter.out statements ) and instead relying on some formatters after your Java program has completed generating your .java files.

Here's some formatters

This looks like a more perfect solution than that for which I asked; thank you very much!

you can either use javaparser to parse the output generated after parsing will be with standard indentation

Can you provide an example?

With Javaparser printing a source code (with default pretty printer) is as simple as that.

CompilationUnit cu = StaticJavaParser.parse(<path to source file>);
System.ou.println(cu.toString());
