Answer:
A constructor doesn't have a return type.
The name of the constructor must be the same as the name of the class.
Unlike methods, constructors are not considered to be members of a class.
A constructor is called when a new instance of an object is created.
Explanation:
Answer:
d. public myClass( ) {. . .}
Explanation:
A constructor is a special method that is called when an object of a class is created. It is also used to initialize the instance variables of the given class. A class may have one or more constructors provided that these constructors have different signatures. A class that does not have a constructor explicitly defined has a default parameterless constructor.
Having said these about a constructor, a few other things are worth to be noted by a constructor.
i. In Java, a constructor has the same name as the name of its class.
For example, in the given class <em>myClass</em>, the constructor(s) should also have the name <em>myClass</em>.
ii. A constructor does not have a return value. It is therefore wrong to write a constructor like this:
<em>public void myClass(){...}</em>
This makes option a incorrect.
iii. When a constructor with parameters is defined, the default parameterless constructor is overridden. This might break the code if some other parts of the program depend on this constructor. So it is advisable to always explicitly write the default parameterless constructor.
This makes option d a correct option.
Other options b and c may also be correct but there is no additional information in the question to help establish or justify that.
package mypackage; // Whatever package this should be in.
public abstract class DesktopComponent {
private String type;
// Alternatively you may want a final variable.
// private final String type;
public DesktopComponent(String type)
{
this.type = type;
}
abstract void onClick();
}
