How to use the toString method in Java?

Question

Can anybody explain to me the concept of the toString() method, defined in the Object class? How is it used, and what is its purpose?

Answer 1

The main purpose of toString is to generate a String representation of an object, means the return value is always a String. In most cases this simply is the object's class and package name, but on some cases like StringBuilder you will got actually a String-text.
