<p data-start="292" data-end="327">Hey everyone,
<p data-start="329" data-end="625">I often see confusion around Java exception handling, especially when it comes to the difference between throws and Throwable. As part of a leading software testing company, we regularly deal with error handling and exception testing in different projects, so I thought I’d share some insights.
<ul data-start="627" data-end="934">
<li data-start="627" data-end="814">
<p data-start="629" data-end="814">throws → Used in method declarations to specify which exceptions might be thrown. It’s basically a way to alert the compiler and developers that a method can cause certain exceptions.
</li>
<li data-start="815" data-end="934">
<p data-start="817" data-end="934">Throwable → This is the superclass of all exceptions and errors in Java. Both Exception and Error extend Throwable.
</li>
</ul>
<p data-start="936" data-end="947">In short:
<ul data-start="948" data-end="1058">
<li data-start="948" data-end="996">
<p data-start="950" data-end="996">throws = a keyword that declares exceptions.
</li>
<li data-start="997" data-end="1058">
<p data-start="999" data-end="1058">Throwable = the root class for all exceptions and errors.
</li>
</ul>
<p data-start="1060" data-end="1187">This distinction is crucial for writing stable, bug-free applications and for creating effective software testing strategies.
<p data-start="1189" data-end="1419">We recently published a detailed article on this topic with code examples and practical explanations. If you want to dive deeper, you can check it out here:<br data-start="1345" data-end="1348" /> https://fleekitsolutions.com/difference-between-throws-and-throwable/
<p data-start="1421" data-end="1543">Would love to hear your thoughts — how do you usually explain this concept to junior developers or testers on your team?
