Two types of variables in Java – primitive variables and reference variables. A primitive type refers a primitive data type and reference type refers a class

The formula is implemented as an anonymous object. The code is quite verbose: 6 lines of code for such a simple calucation of sqrt(a * 100).

Learn about upcoming language features in Java 8, as well as the most important enhancements to the standard libraries, specifically the new Stream interface.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: For example, if an object that has three fields, x, y, and z, one could write: @Override public int hashCode() { return Objects.hash(x, y, z); } Warning: When a single object reference is supplied, the returned value does not equal the hash code of that object reference. This value can be computed by calling hashCode(Object).
