Difference between Abstract Class and Interface in Java ?

The blog covers the detailing about abstract class and interfaces in java. 

buy modafinil bangkok What is an Abstract Class in java ?

• An abstract class contains the abstract method ( without body /implementation) and concrete methods (methods with implementation)
• An abstract class is defined using the keyword “abstract” 
• A class can override the methods of abstract class by implementing them
• An abstract class can not be instantiated i.e., cannot have an object creation
• As an abstract class can have concrete methods, it supports partial abstraction

For instance, consider an abstract class example with methodOne() , methodTwo() and methodThree() where the methodThree() is a concrete method with the body .

package core.java.planforexams.oops;

abstract class AbstractExample {

abstract void MethodOne();

abstract void MethodOTwo();

//This is concrete method with body
void MethodThree(){
System.out.println (" This is a concrete method in anstract class.. ");
}
}

An interface in java provides the abstract methods ( without implementation) and thus supports full abstraction.

For instance, consider the student marks interface example in java 

Create an interface StudentMarksInterface  with abstract method getMarks() 

Create the class StudentMarks that implements StudentMarksInterface and overrides the getMarks() 

package core.java.planforexams.oops;

interface StudentMarksInterface {

public int getMarks();
}

package core.java.planforexams.oops;

public class StudentMarks implements StudentMarksInterface {

public int getMarks()
{
System.out.println("Implemnts the getMarks() in classs StudentMarks... ");
return 0;
}

public static void main(String arg[])
{
StudentMarksInterface obj = new StudentMarks();
obj.getMarks();

}

}

The below given are the major differences between abstract class and an interface in java
