Java Tip #1. Stop to use "toString" method!

When you need to get string value of some object you should use String.valueOf method.
The String.valueOf method is null-safe and more clear way to get string value of the target object.

class SomeClass {
    @Override public String toString() {
        return "String value of SomeClass instance!"
    }
}

public class Main {
    public static void main(String[] args) {
        SomeClass someClassInstance = new SomeClass();

        System.out.println(String.valueOf(someClassInstance));
    }
}
