    Please write better topic/thread titles. "Java" isn't helpful. "Tell me about constructors" is much better and would alert people that you're asking for basic info that could be easily found in several hundred places on the web and in every Java textbook that's ever been written.

    a constructor is called when you use the 'new' keyword.

    Is is called when you create a Java object.

    e.g.:

     
    public MyClass()
    {
         // this is the constructor so you would initialise variable etc within this.
         // it is called when you instantiate the object
    }
     
     
     
    MyClass mc1 = new MyClass();                  <----- this will create the object and call the MyClass method (constructor) so anything within the constructor is called at this point.


    You really need to learn Object Orientated Programming and the concept of objects etc.

    To be fair your question was poorly written so dont expect any great responses.
