Print whole structure with single call (like JSON.stringify) in Java?

Question

How to print any class instance in Java? Similar to JSON.stringify() in Javascript. Not necessary JSON, any format of output will do.

public class User {
    pub         


        

Answer 1

You can use Apache's commons-lang's ToStringBuilder.reflectionToString

Of course, reflection is slow, so only do this with your test code. for normal use, please use eclipse's "Source" menu -> generate toString() (or intellij's generate toString()) which gives you a decent string.
