    copied!<p>As a rule, the <code>finally</code> block is always executed whether or not an exception is thrown in the <code>try</code> block or a <code>continue</code>, <code>break</code> or <code>return</code> statement encounters in the <code>try</code> block itself.</p> <p>Accordingly, the return value of the method in the code snippet given below should be changed but it doesn't.</p> <pre><code>final class Product { private String productName=null; public Product(String productName) { this.productName=productName; } public String getProductName() { try { return this.productName; } finally { this.productName="The product name has been modified in the finally block."; System.out.println("Product name in the finally block : "+this.productName); } } } public final class Test { public static void main(String...args) { System.out.println(new Product("Intel core i3").getProductName()); } } </code></pre> <p>The method <code>getProductName()</code> simply returns the product name which is assigned by the constructor to the field <code>productName</code> before this method is invoked.</p> <p>Before this method returns, the value of <code>productName</code> is modified in the <code>finally</code> block. Therefore, the method should return this new modified value but it returns the initial value which is assigned to <code>productName</code> when an instance of this class has been constructed.</p> <hr> <p>It produces the following output:</p> <blockquote> <p>Product name in the finally block : The product name has been modified in the finally block.<br> Intel core i3</p> </blockquote> <p>Why doesn't this method return the new value which is assigned to the <code>productName</code> field in the <code>finally</code> block? It should return the new value. Shouldn't it?</p>
