Hello World in Unicode - java

\u0070\u0075\u0062\u006C\u0069\u0063\u0020\u0063\u006C\u0061\u0073\u0073\u0020\u0055\u006E\u0069\u0057\u0072\u006C\u0064\u007B\u0070\u0075\u0062\u006C\u0069\u0063\u0020\u0073\u0074\u0061\u0074\u0069\u0063\u0020\u0076\u006F\u0069\u0064\u0020\u006D\u0061\u0069\u006E\u0028\u0053\u0074\u0072\u0069\u006E\u0067\u005B\u005D\u0020\u0061\u0029\u007B\u0053\u0079\u0073\u0074\u0065\u006d\u002E\u006F\u0075\u0074\u002E\u0070\u0072\u0069\u006E\u0074\u006C\u006E\u0028\u0022\u0048\u0065\u006C\u006C\u006F\u0020\u0077\u006F\u0072\u006C\u0064\u0022\u0029\u003B\u007D\u007D


Save the content in UniWrld.java and execute it. It will print Hello World. According to java language specification java compiler parses the source code in unicode characters. So if we can write the entire program in unicode alone. 

See the following code and guess the output.

public class HelloWorld 
{
public static void main(String[] args) 
{
// \u000d System.out.println("Hello world");
}
}

Instead of printing nothing it will print Hello world because the unicode \u000d corresponds to line return and put the content System.out.println("Hello world"); in a new line. So all your source code are converted into unicode and then converted into byte code.

The evolution of Lambda

Hi Guys,              Let us look at the behavioral parameter pattern, the base of lambda function and the evolution of  lambda function. Change is inevitable. Requirements do change.

Let us discuss with an example. Requirement: We have a list of employees. We want to filter only full time employees. How can we write java code for this. Solution 1:  public List<Employee> filterFulltimeEmployee(List<Employee> employees) { List<Employee> filteredEmployees = new ArrayList<>(); for(Employee employee : employees) { if(employee.isFulltimeEmployee) filteredEmployees.add(employee); } return filteredEmployees; } Fine. Now instead of full time employees, we need part time employees. A naive solution would be ...
