Java 8 Garbage Collection Explained for Senior Engineers | Optimize Heap Memory | Cognizant Intervw

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...
