How to declare a constructor in Java?

While declaring the constructors you should keep the following points in mind.

• A constructor does not have a return type.
• The name of the constructor is same as the name of the class.
•  A class can have more than one constructor.

Example

public class Sample {
   int num;
   public Sample() {
      num = 30;
   }
   public Sample(int value) {
      num = value;
   }
}
