The code above is executed as shown below: Run Command javac InputOutputExceptionExample.java ("This is not printed") Ĭatch (FileNotFoundException fileNotFoundException)įileNotFoundExceptionExample example = new FileNotFoundExceptionExample() Public class FileNotFoundExceptionExampleįileInputStream in = new FileInputStream("input.txt") In the following example, we are going to try to read some lines of text from a file that does not exist: IOException import java.io.FileInputStream Let’s see a very simple case of a Java IOException. Throw new ApplicationException("IO Exception in Manager" ,ioException) Throwing an application exception after catching an IOException is presented in the code below: Throwing an application exception try Throw new BusinessException("IO Exception in Service" ,ioException) In the code below, throwing a business exception after catching the IOException is shown. Throw new WrappedException("IO Exception in Facade" ,ioException)
In the code below, a wrapped exception is thrown after catching IOException in Facade class. Throw new RuntimeException("IO Exception in CommandLine Application",ioException) In the code below, a runtime exception is thrown after catching the IOException in a java application. The code below shows the printing of the exception stack trace. Try catch finally block of code is shown below in different scenarios. The application API class methods throw an IOException or its subclasses. In a method of a class, try, catch, and finally block handles the exception. java.io.IOException is the base exception class used for handling the failures. Java application needs to handle failures related to reading, writing, and searching a file or a directory. The sequence diagram of throwing the IOException in classes Manager, Service, Facade, and Persistence Manager is shown below: IO Exception Sequence Diagram 6. The programmer needs to subclass the IOException and should throw the IOException subclass based on the context. Java.io.IOException is an exception which programmers use in the code to throw a failure in Input & Output operations. What is Java IOException – java.io.IOException They can be set as shown below: Setup JAVA_HOME="/desktop/jdk1.8.0_73"Ĥ. You can set the environment variables for JAVA_HOME and PATH. Java 8 can be downloaded from the Oracle website.

Java 7 or 8 is required on the Linux, windows, or Mac operating system. SSLException happens when the SSL connection is not established. When the socket connection is closed, SocketException can happen. If the file has an unsupported encoding, UnsupportedEncodingException occurs. While reading a file, EOFException occurs when the end of the file is reached. If the file is not found, FileNotFoundException is thrown. IOException has subclasses such as FileNotFoundException, EOFException, UnsupportedEncodingException, SocketException, and SSLException. This exception object has a string message which is the root cause for the failure. A checked exception is handled in the java code by the developer.
It happens when there is a failure during reading, writing, and searching file or directory operations. This exception is related to Input and Output operations in the Java code.
