This tutorial will guide you on various inheritance types available in Java. You will know about each of them using sample Java programs.
Types of Inheritance in Java
You can go through the following sections to learn about Types of Inheritance in Java.
As discussed before_inheritance is one of the important concepts in Object Oriented Programming Language. It is the process through which an already existing class extends its features to a new class. Java supports various kinds of inheritance.
Single Inheritance
As the name would suggest, single inheritance_is simply one subclass extending one superclass. It is the simplest of all. The general syntax to implement single inheritance_is given below. Here class Parent is the superclass and Child is the subclass.
class Parent
// methods
// fields
// ……
class Child extends Parent
// already supports the methods and fields in Parent class
// additional features
Fig – 1
The example below will help you visualize the implementation of single inheritance.
class Calculator
int add(int a , int b)
return a+b;
int sub(int a , int b)
return a-b;
public class AdvancedCalculator extends Calculator
int mult(int a , int b)
return a*b;
int div(int a , int b)
return a/b;
public static void main(String args)
AdvancedCalculator cal= new AdvancedCalculator();
System.out.println(cal.add(1,2)); www.myprogrammingschool.com/2020/10/java-inheritance-type...
Java Files and directories
Files in Java is a class that is part of the java.io package which we use to perform different operations on files. A file is a repository that stores information. For example, the .java file that we create is a file that contains details about the Java program.
A directory is a collection of files that are saved in a particular location.
In order to perform the file operations, the Java Files class uses the stream concept.
Java Stream
In Java, a stream is a sequence of data. We can classify stream into two types as InputStream and OutputStream. InputStream is used to read input data and we use OutputStream to write data into the output file.
We can also classify streams into ByteStream and CharacterStream.
ByteStream: This performs read and write operations on 8-bit data. The FileInputStream and FileOutputStream are examples of the ByteStream.
CharacterStream: This performs read and write operations on 16-bit data. The FileReader and FileWriter are examples of the CharacterStream.
Java Files Constructors
Below are the constructors that the File class in Java supports.
Java Files Methods
Files operations in Java
The common operations that we perform on Files in Java are:
- Create a file
- Get file information
- Write into a file
- Read a file
- Copy file
- Set file permissions
Let's understand these file operations with simple examples.
Create
In this tutorial, we will see the different approaches on how to find the smallest number in an array in Java.
Sort and swap technique
In this method, we actually compare the 1st element with the 2nd element and sort the elements in ascending order using a third variable. In this way, after sorting, the first array element will be the smallest number in the array.
Algorithm
- Initialize an array variable arrValues with array values.
- Next, initialize an int variable small and assign it as arrValues - This variable holds the first element by default.
- Initialize outer for loop starting from 0 until array length.
- Initialize inner for loop starting from i+1 until array length.
- Compare arrValues > arrayValues
- If true, swap the values using the small variable.
- If false, move to the next iteration within the inner for loop
- Continue steps 3 to 7 until it reaches the end of iteration in outer for loop.
- Finally arrValues variable contains a sorted array list in ascending order.
- Hence arrValues contains the smallest element.
Java program: How to find the smallest number in an array
Below is an example that shows how to find the smallest number in an array Java using the sort and swap technique using a third variable.
public class SmallNumDemo1 {
public static void main(String args) {
int arrValues = {23,56,12,85,68};
int small = arrValues;
for(int i=0;i

What Is Method Overriding In Java?
Join telegram for daily updates:- t.me/corejavatopics
Method Overriding In Java? It is the process of providing the subclass specific method implementation and Logic for the inherited method. If the subclass provides the particular implementation of any method, which is declared by its superclass, is known as method overriding in java.
When the method is inherited in the superclass to subclass, then in the subclass, we can change the Method Logic by keeping the same declaration as declared in the superclass.
Method overriding is possible only in the case of Inheritance.

Method overriding rules in java?
The method must be inherited in the superclass to the subclass.The return type of method must be the same as declared in the superclass. The method name must be the same as declared in the superclass.Method name, context type, or a signature must be the same as declared as in the superclass, but Logic can be different. Access modifications must be the same as declared in the superclass or can be of higher visibility.We can optionally use annotation (@Override) called an override (annotation is introduced from JDK 1.5)
Usage of Java Method Overriding?
Method overriding is used to implement a specific implementation of a method that is already provided by its superclass. bit.ly/3k50phO
In some situations, while executing a Java program from the command prompt, we may face the error "Could not find or load main class". This occurs mainly when the JVM fails to find the main class or .class file. Whenever we compile a Java code, the compiler will automatically create a .class file with the same name as the class name. This will be present in the same directory where we have the .java file.
Let us see a simple Java code and try to compile and execute it from the command prompt.
public class HelloJava {
public static void main(String args) {
System.out.println("Java programming language");
}
}
First, we need to compile the code using the javac command.
D:Sample>javac HelloJava.java
This will produce the right result as below since we have compiled it correctly.
D:Sample>java HelloJava
Java programming language
Now let us see the different reasons or causes to generate the error "Could not load or find the main class in Java".
Could not find or load main class in Java: Incorrect class name
Whenever we compile the java code, the compiler creates a .class file in the same name as the class name. After compilation, if we try to run the code by providing an incorrect file name in the java command, it will result in an error "Could not load or find the main class in Java".
D:Sample>java hellojava
Error: Could not find or load main class hellojava
Caused by: java.lang.NoClassDefFoundError:

About Java 11
It is advised to use Java 11 JDK which is a latest version of Java development kit in 2018. JDK helps you to compile Java programs and run your Java program using Java Virtual machine (JVM). You need Java development kit (JDK) to write Java programs.
Oracle is now the owner of Java and they started charging for Java. Students and programmers actually don't need to pay anything to use Oracle's version Java. Now Oracle have moved to LTS model (Long Term Support) where they will support a particular version of Java for a long time but other versions will expire and no longer be supported by Oracle.
Java 9 or Java 10 are no longer supported by Oracle. So we should not use any version of Java lower than 11. Java 11 is the version of Java which Oracle has put in long-term support (LTS) and will support for many years.
New features in Java comes every 6 months. For example Java 12 will come during March 2019 and Java 13 will come in September 2019. These are feature versions so will get expire after six months after their release date.
Companies which work in Java are standardizing Java 11 and we should also start working on Java 11.
Installing Java 11
