1. Create a Java class named Package that contains the following:a. Package should have three private instance variables of type double named length, width, andheight.b. Package should have one private instance variable of the type Scanner named input, initializedto System.in.c. No-args (explicit default) public constructor, which initializes all three double instance variables to1.0.d. Initial (parameterized) public constructor, which defines three parameters of type double,named length, width, and height, which are used to initialize the instance variables of same name.e. Public copy constructor, with a parameter of type Package, used to duplicate anexisting Package object.f. Three public void methods named inputLength, inputWidth, and inputHeight. Each methodwill prompt the user for the appropriate property, and input a double value usingthe Scanner…
