Here we are describing the use of using exception class in java .Exceptions handling is the way in Java to handle run time errors and to indicate a calling method that an abnormal condition has occurred.
Example to show exception handling in java
In this Tutorial we want to describe you a code that show you the use of exception class in java .Exceptions handling is the key in Java, that handle run time errors and indicate a calling method whenever an abnormal condition occurred. This tutorial helps you in understanding exception handling appropriately in programs and designs. The steps involved in the program are described below:-
BufferedReader br = new BufferedReader(new FileReader("girish")):-Buffered reader is a class that reads text from a character-input stream. Here we are creating Buffered reader which generally read request made of a Reader.
String s = br.readLine():- This method read each line of the text and buffer request is stored in the string s.
System.out.println("File not found."):-This is the Exception message which is to be displayed if the particular file is not found.
SimpleExceptionHandling.java
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
public class SimpleExceptionHandling {
public static void main(String args[]){
try{
BufferedReader br = new BufferedReader(new FileReader("girish"));
String s = br.readLine();
System.out.println(s);
}
catch(FileNotFoundException fne)
{
System.out.println("File not found.");
}
}
}
Output of the program
| File MyFile.txt not found. |
