serialization - Casting Character to char and char to Character Java -


can please explain me why code working fine?

import java.io.*;  public class array {     public static void main(string[] args) throws ioexception, classnotfoundexception {         fileoutputstream fo=new fileoutputstream("character.dat");         objectoutputstream oos=new objectoutputstream(fo);         fileinputstream fi=new fileinputstream("character.dat");         objectinputstream ois=new objectinputstream(fi);         character c = 'h';         oos.writeobject(c);         character arr = (char)ois.readobject();         system.out.println(arr);         fo.close();         fi.close();         oos.close();         ois.close();     } }

in line 10, have created character , have serialized in line 11 , written file. in line 12, have deserialized object, returns reference of object, have downcast character. in line 12, downcasting char (which primitive data type , not class) , still working fine. why that?

i think cast object char , assignment character still working because of java's autoboxing going on behind scenes. link might explain more in depth.

What Are The Best Universities In The World?

Harvard and Yale are often referred to as “the best of the best”. But when it comes to the highest ranked universities, these and other Ivy League schools don't even make it into the top five. So what are the world's best universities? Well, according to an index by the Times Higher Education, Stanford ranks 3rd in the world. Most people associate Stanford with tech-capital Silicon Valley, which is where the school is located. And in fact, it's largely because of Stanford that the region is now the global capital of entrepreneurship and technology. In the 1940's and 50's the university heavily encouraged students and faculty to start their own companies, eventually leading to companies like Google and Snapchat. And still today, the school is known to produce some of the most successful entrepreneurs. A Stanford degree is in extremely high demand, and the school maintains the lowest acceptance rate in the country, admitting less than 5 percent of applicants. Much ...

The Ten Most Livable Cities In The World

Every year, the Economist Intelligence Unit releases its ranking of the “most livable cities” in the world. Therein, they attempt to quantify what exactly makes living in a city better or worse. It generally breaks down into five categories: stability, healthcare, culture and environment, education, and infrastructure. So, what are the world's most livable cities? Well, in fact, the top seven cities actually comprise just three countries, with six countries total in the top ten. Although it is not true everywhere, countries with effective policies tend to see positive effects country-wide. However, many major cities around the world can actually be victims of their own success. Cities like New York City or London are world renown, but also have higher crime rates, overpopulation leading to infrastructure failure, and often much higher costs of living. The cities in this list are able to avoid those pitfalls. The top ranked city in the world is Melbourne Australia, a title it has...

Hard vs. Soft Water: What's The Difference?

Hard or Soft? HOW AM I SUPPOSED TO KNOW? THEY BOTH LOOK EXACTLY THE SAME! Hey there, Sapna here for Dnews. From the outside, all water is seemingly the same: clear, mostly flavorless, two hydrogens, one oxygen. But once you get past the basics, water is actually pretty versatile. It can be distilled, filtered, tap, bottled, and if you're real fancy, there's water marketed as kosher, organic or kabbalah. But did you know water can also be hard or soft? No, this isn't to describe how the water actually feels. It actually has to do with its mineral content. Water becomes ‘hard' when it has a higher than normal concentration of minerals, primarily calcium and magnesium. Water picks up these minerals from rocks and soil as it flows through rivers, wells or other waterways. Soft water, on the other hand, has a low mineral content, either because it has not yet flowed through rocks or wells - like rain water - or because the rocks it has come in contact with have little to no...
