Why ioexception

Click to see full answer. Simply so, what is meant by IOException in Java? It is generally used in IO file. Secondly, how do you handle IOException? In a method of a class, try, catch, and finally block handles the exception. The application api class methods throw an IOException or its subclasses. Try catch finally block of code is shown below in different scenarios.

It can throw an IOException when the either the stream itself is corrupted or some error occurred during reading the data i.

Suppose you have a function input where you are using BufferedReader class to take input. So you shall be throwing the IOException from that input method. Now, when you call that method from another method, that method must also throw tha. The throws keyword indicates that a certain method can potentially " throw " a certain exception. You need to handle a possible IOException and possibly other exceptions either with a try-catch block or by adding throws IOException , to your method declaration.

What is the use of throws keyword in Java? The Java throws keyword is used to declare an exception. It gives an information to the programmer that there may occur an exception so it is better for the programmer to provide the exception handling code so that normal flow can be maintained. Exception Handling is mainly used to handle the checked exceptions. Is IOException checked? You don't need to handle or declare it to be thrown in method throws clause Here I mean, it would be syntactically correct if you don't handle the unchecked exception.

Compiler won't be angry. What is BufferedReader in Java? BufferedReader is a class in Java that reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, lines and arrays.

It may occur due to the file deleted or viruses in the file. Sometimes BufferedReader takes data from a network stream where the reading system can fail at any time. Attention reader! Get hold of all the important Java Foundation and Collections concepts with the Fundamentals of Java and Java Collections Course at a student-friendly price and become industry ready. So this type of error can occur in input operation when a BufferedReader is used. This is why a buffered reader throws IOException.

Below is an example of BufferedReader use. Skip to content. Change Language. Related Articles. IOException String. IOException String, Exception. IOException String, Int Inherited from Exception. Gets or sets a link to the help file associated with this exception.

Gets a message that describes the current exception. Gets or sets the name of the application or the object that causes the error. Gets a string representation of the immediate frames on the call stack. Gets the method that throws the current exception.
