This is an example
class MyClass{
public MyClass(){
System.out.println("Constructor without parameters");
}
public MyClass(int a){
//overloaded constructor
System.out.println("Constructor with 'a' parameter");
}
}
You can create multiple "versions" of the class constructor. This is the meaning of method overload. You can overload almost any method of a Java class.
Take a look to official Java tutorial at http://docs.oracle.com/javase/tutorial/
More information on http://docs.oracle.com/javase/tutorial/java/javaOO/methods.html and http://www.java-samples.com/showtutorial.php?tutorialid=284

Thank you Lobo...It has helped a lot..
Consider the code below, the constructor is overloaded and can be called either with...
new Tester();
or
new Tester("Hello world!");
These would both be valid in the given class
class Tester {
public Tester() {
}
public Tester(String overloaded) {
System.out.println(overloaded);
}
}
