public class Test {
public static void main (String args []) {
new Test();
}
public Test () {
System.out.println(this);
}
}
output: Test@affc70
why no error?
What's the meaning about printing the class itself?
thanks for help

The Object class has a toString() method, which is inherited by all its subclasses (which means all classes), unless overriden.
What you see printed out is the default toString() method, which shows the class name and its hashcode. Kinda useless, though, so you might wanna override the toString() method in your class.
