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:

In Java Persistence API you use them to map a Java class with database tables. For example @Table () Used to map the particular Java class to the date base table. @Entity Represents that the class is an entity class. Similarly you can use many annotations to map individual columns, generate ids, generate version, relationships etc.
I always thought that && operator in Java is used for verifying whether both its boolean operands are true, and the & operator is used to do Bit-wise operations on two integer types.
In Java, == and the equals method are used for different purposes when comparing objects. Here's a brief explanation of the difference between them along with examples:
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...
The Java jargon uses the expression method, not functions - in other contexts there is the distinction of function and procedure, dependent on the existence of a return type, which is required in a ternary expression.
12 In Java there is a difference between x++ and ++x ++x is a prefix form: It increments the variables expression then uses the new value in the expression. For example if used in code:
