Use String.valueOf() instead of toString() 💎

If obj needs to be converted to string then the result of obj.toString() and String.valueOf(obj) will be same.

But String.valueOf() is Null Safe, means it will never throw NullPointerException. 🎯

Test test = null;

// Below statement will not throw NPE
System.out.println(String.valueOf(test));

// Next statement will throw NPE
System.out.println(test.toString())
