Java toString Method

toString is another method belonging to the Object class. The default behavior is to return the name of the class, followed by an @ then the hash code of the object in hexadecimal. toString can be invoked explicitly as in
System.out.println(emp2.toString());

resulting in something like:

Employee@f97

toString is also invoked implicitly by Java when concatenating a non-String object with a String, as in

System.out.println("emp2 is " + emp2);

toString
public String toString()
{
return ''Employee[" + empNumber + ", " + name + ", " + salary + "]";
}


The statement

System.out.println(emp2.toString());

will now output

Employee[2, Sim, 15000]
