Have you ever encountered a situation where your Java exception lacks a message? 🤔 Here's a quick overview of why this happens and how to handle it like a pro.
In Java, exceptions can be thrown without a specific message, leading to potential confusion. The NullPointerException is a common culprit, especially when you expect more informative messages.
To illustrate:
try { String str = null; // This will throw a NullPointerException System.out.println(str.length()); } catch (NullPointerException e) { System.out.println(e.getMessage()); // This will print 'null' }
When handling exceptions, consider these best practices:
- Always provide meaningful messages when throwing exceptions. - Use custom exception classes if standard ones don't fit your context. - For debugging, use logging frameworks to capture full stack traces instead of just messages. 📊
In summary, never underestimate the power of a clear exception message. It can save hours in debugging! 🚀

I have no inside knowledge of a potential stock listing of the popular anti-Whatsapp messaging app, Telegram. But I know this much, judging by most people I talk to, especially crypto investors, if Telegram ever went public, people would gobble it up. I know I would. I’m waiting for it. So is Sergei Sergienko, who claims he owns $800,000 of Telegram’s pre-initial coin offering (ICO) tokens. “If Telegram does a SPAC IPO, there would be demand for this issue. It would probably outstrip the interest we saw during the ICO. Why? Because as of right now Telegram looks like a liberal application that can accept anyone - right after WhatsApp and others have turn on the censorship,” he says.
Spiking bond yields driving sharp losses in tech stocks
A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year.
A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
