Is short-circuiting logical operators mandated? And evaluation order?
...&& operator groups left-to-right. The operands are both implicitly converted to type bool (clause 4).

What are the differences between Generics in C# and Java… and Templates in C++? [closed]
...oesn't understand these new List<something>, so you have to manually convert things back to plain old List to interoperate with them.

What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it?
...ts to iterate over when doing this, and your [corrected] example is easily converted over.
The code below:
String[] name = {"tom", "dick", "harry"};

System.out.print(name[i] + "\n");
}
...is equivalent to this:
String[] name = {"tom", "dick", "harry"...
