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{
exception 1.....
}
catch{
exception 2.....
}
................
.................
catch{
exception n.....
}
finally
{
System.out.print(" I am a finally block");
System.out.print(" I always executed exception handled or not");
}
}

Program

public class try_keyword{
    public static void main(String args[]){
        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

 

 

In the program, the finally block contains an important statement that must be executed whether an exception occurs or not

finally block always to be associated with the try block, never we can use finally without the try block
