The finally keyword in Java programming language

We will learn in this tutorial about The finally keyword in Java programming language

The finally is a keyword of Java, is an optional part of a try block using exception handling in Java. When an exception is thrown inside a try block, the exception will be compared to any of the catch parts of the inside in try block .when the compare exception with catch block, the exception may match or not any catch block.

However, Java finally block is having a block of code.which is always executed whether the exception is handled or not

The finally clause is optional part in the try block. However, each try block requires at least one catch or finally clause.

try{
block of code......
catch{

catch{
exception n.....
}
finally
{
System.out.print(" I am a finally block");
System.out.print(" I always executed exception handled or not");
}
}

        try{//try block for exception handling
            int a[]=new int[5];
            a[6]=45;

            finally{System.out.println("I always executed\n");
    }
    }
}

When the above code is compiled and executed, it will produce the following result
