Document Summary

The this keyword is use to refer to the object on which a non-static method was called. Instead of passing v as input, we can use the this keyword inside the print method to refer to it. No! this refers to the object instance that calls the method. A static method is called from the name of the class, and not from a particular object. The static method wold have nothing to refer to. In a static method, you would use the name of the class instead of the word this if you wanted to specify the global vs local variable. Add a method getmagnitude to the vector class. Recall that the magnitude of a vector v with dimension d. We"ll make this static, so you don"t need to pass a vector as input, you can call it on a particular vector.
