Java Output Format With Indents As Code:

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 开发者_开发技巧will handle indention and such of outputted code.

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

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

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());
