I didnot understand this example clearly.
why will someone implement a function like :
private static Rectangle getNewRectangle()
{

return new Square();
}

when we want a rectangle. this looks like a coding error

Java

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
