Web Reference: Jan 2, 2010 · 7 It is the Bitwise xor operator in java which results 1 for different value of bit (ie 1 ^ 0 = 1) and 0 for same value of bit (ie 0 ^ 0 = 0) when a number is written in binary form. ex :- To use your example: The binary representation of 5 is 0101. The binary representation of 4 is 0100. Not only in Java, this syntax is available within PHP, Objective-C too. In the following link it gives the following explanation, which is quiet good to understand it: A ternary operator is some operation operating on 3 inputs. It's a shortcut for an if-else statement, and is also known as a conditional operator. In Perl/PHP it works as: While hunting through some code I came across the arrow operator, what exactly does it do? I thought Java did not have an arrow operator. return (Collection<Car>) CollectionUtils.select(list...

YouTube Excerpt: A program's memory usage typically includes four different regions: Code — The region where the program instructions are stored. Static memory — The region where static fields and local variables (variables declared inside methods starting with the keyword "static") are allocated. The name "static" comes from these variables not changing (static means not changing); they are allocated once and last for the duration of a program's execution, their addresses staying the same. Stack — The region where a method's local variables are allocated during a method call. A method call adds local variables to the stack, and a return removes them. Heap — The region where the "new" operator allocates memory for objects. The region is also called free store. In Java, the code and static memory regions are actually integrated into a region of memory called the method area , which also stores information for every class type used in the program.
