Solution

The output of the given Java code will be:

Try block is running
Finally Block :20
Main Block:20

Here's the step by step explanation:

  1. The main method is the entry point of the program. It creates an instance of the HackerEarth class and calls the getValue method on it.

  2. Inside the getValue method, an integer returnValue is declared and initialized with the value 10.

  3. Then a try block is executed. Inside this block, an array of Strings Languages is declared and initialized with two elements. The second element of this array is printed to the console. Since there is no error in this block, the catch block is skipped.

  4. After the try and catch blocks, the finally block is executed. Inside this block, the value of returnValue is incremented by 10, making it 20. This new value is then printed to the console.

  5. After the finally block, the method returns the value of returnValue, which is 20. This value is printed to the console in the main method.
