Java Program to Handle the Exception Using Try and Multiple Catch Block

This is a Java program to handle the Exception using Try and Multiple Catch Block.

A Java exception is an error condition that has occurred in a piece of code on violation of some rules.
Java Exception Handling is managed via five keywords: try, catch, throw, throws, and finally.

Here is the source code of the Java Program to Handle the Exception Using Try and Multiple Catch Block. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

```
import java.io.FileInputStream;

            Scanner s=new Scanner(System.in);

            System.out.print("Enter a:");

```
            a=s.nextInt();

```
            System.out.println(f);
```
```
            FileInputStream fis = null;
```

            /*This constructor FileInputStream(File filename)

```

            fis = new FileInputStream("B:/myfile.txt");

```
            int k; 
```

            /*Method read() of FileInputStream class also throws

            * a checked exception: IOException*/

            while(( k = fis.read() ) != -1)

```
            { 
```
```
		System.out.print((char)k); 
```
```
            }    
```

            /*The method close() closes the file input stream

```
            * It throws IOException*/
```
```
            fis.close(); 	
```
```
        }
```

        catch(IndexOutOfBoundsException e)

```
        {
```
```
            System.out.println(e);
```
```
        }
```
```
        catch(NullPointerException e)
```
```
        {
```
```
            System.out.println(e);
```
```
        }
```
```
        catch(ArithmeticException e)
```
```
        {
```
```
            System.out.println(e);
```
```
        }
```
```
        catch(Exception e)
```
```
        {
```
```
            System.out.println(e);
```
```
        }
```
```
    }
