methods

问题 This question already has answers here : Definition of a method signature? (7 answers) Closed 4 years ago . I read a book titled 'Object First with Java' and in page 7 the author mentioned that the method signature "provides information needed to invoke that method". And the the author gave the following example: void moveHorizontal(int distance) However, today when I was watching a video about C# on Pluralsight, the author said that "the return type of a method is not part of the method

问题 I'm trying to use a specific code but it won't work for some reason. I have to methods in the same class: public void InputEnter() { if(Input.GetKey(getCoords)) { Move(GetTransform().GetPos()); System.out.println((GetTransform().GetPos())); } } this method gives me some coordinates of Vector3f once I hit enter. The other code writes to a file. public void ProcessText() { System.out.println("ProcessText Operational"); String file_name = "C:/Users/Server/Desktop/textText.txt"; try {

问题 So I'm making a Binary to Decimal converter and I'm supposed to catch the invalid character if the user inputs an illegal argument. I believe I have the correct method for catching any characters that aren't 0 or 1. However, when I try to implement this method into my primary method parseBinary, it says that it "Cannot Find Symbol" for illegal(iChar). I can't add any more parameters to parseBinary because the user is only supposed to enter one string of 0's and 1's. I'm curious if I made this

问题 I have two classes, one called Driver and another called BankAccount. In Driver there is a method called Driver, and in BankAccount a method called Deposit. I'm getting an error that says, "non-static method Deposit() cannot be referenced from a static context" when I try to call BankAccount.Deposit from my Driver method. Any advice on what I should do to these lines of code to make it run. import javax.swing.JOptionPane; public class Driver { int choice; String number; //public Driver()

问题 There are examples of calling such methods on any class. I.e.: SampleClass sc=new SampleClass(); sc.someMethod(); Or is it better to use new SampleClass().someMethod(); Please, explain in detail. 回答1: Both options are as good, but first one is better... If you use SampleClass sc=new SampleClass(); sc.someMethod(); You can call other methods of this class using same object of class. If you use new SampleClass().someMethod(); You require another object to call other method of this class. Other

问题 Hello everyone my name is Fyree!
