Finally Block in Java

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 independently 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

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

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
