What will happen when the following code is compiled and executed?


00: package test;
01: public class Test {
02:     public static void main(String [] args) {
03:          Test test = new Test();
04:          System.out.println(test.toString());
05:     }
06: }

Compilation error in line 03, as the class Test is not defined by the constructor
Compilation error in line 04, as the class Test does not define the method toString()
The code will compile, but during the launch exception java.lang.NoSuchMethodError will be thrown in line 04
The code will compile and display the following:
Test
The code will compile and display something like the following:
test.Test@42e816

Explanation

All objects in Java are inherited from the Object class. Since a Test class does not override a toString() method, it will use its Object class implementation, which returns a string representation of the object as follows: class name (with a full package name) + @ symbol + hexadecimal unsigned value of object's hash code
