Introduction
It is a special block in Java. It is a block in a program that always executes. If we want to perform an important task and want it to execute always in any condition then we use a finally block in Java.
Finally Block in Java
The following describes the finally block in Java:
- In Java, finally is a special keyword.
- It always executes independent of any condition.
- It is optional in Java.
- It should be after the try-catch block in Java.
- For a single try block, there can be a maximum of one finally block in Java.
- Generally we use a finally for closing the connections or closing the file and so on.

Examples of Finally in Java
No Exception Condition
package demo;
public class Demo
{
public static void main(String args[])
{
try
{
int fig=36/6;
System.out.println(fig);
}
catch(NullPointerException e)
{
System.out.println(e);
}
finally
{
System.out.println("ALWAYS EXECUTE");
}
System.out.println("#**.......**#");
}
}
Output
![when no exception]()
Exception Condition
package test;
public class Test
{
public static void main(String args[])
{
try
{
int fig=36/0;
System.out.println(fig);
}
catch(NullPointerException e)
{
System.out.println(e);
}
finally
{
System.out.println("ALWAYS EXECUTE");
}
System.out.println("#**.......**#");
}
}
Output
![when exception]()
Exception Condition, But Handled
package trial;
public class Trial
{
public static void main(String args[])
{
try
{
int fig=36/0;
System.out.println(fig);
}
catch(ArithmeticException e)
{
System.out.println(e);
}
finally
{
System.out.println("ALWAYS EXECUTE");
}
System.out.println("#**.......**#");
}
}
Output
![exception but handled]()
