method initialize(int,int,int) is already defined in class com.codegym.task.task05.task0513.Rectangle: Rectangle.java, line: 30, column: 17

Question about the task

Let's put together a rectangle

Java Syntax, Level 5, Lesson 7

Under discussion

Hey, the error says that i can't create 2 initialize() with the same data type parameters... why is that?

com/codegym/task/task05/task0513/Rectangle.java:30: error: method initialize(int,int,int) is already defined in class com.codegym.task.task05.task0513.Rectangle
    public void initialize(int top, int left, int height) {
                ^
com/codegym/task/task05/task0513/Rectangle.java:38: error: method initialize(int,int,int) is already defined in class com.codegym.task.task05.task0513.Rectangle
    public void initialize(int top, int left, int width) {
                ^

Create a Rectangle class. The data for this class will be top, left, width, height.
Create as many initialize(...) methods as possible

Here are some examples:
- 4 parameters are specified: left, top, width, and height
- width/height is not specified (both are 0)
- height is not specified (it is equal to the width), we'll create a square
- create a copy of another rectangle passed as an argument

Requirements:

The program must not read data from the keyboard.
The Rectangle class must have int variables top, left, width and height.
The class must have at least one initialize method.
The class must have at least two initialize methods.
The class must have at least three initialize methods.
The class must have at least four initialize methods.

package com.codegym.task.task05.task0513; /* Let's put together a rectangle */ public class Rectangle { //write your code here int top; int left; int width; int weight; public static void main(String[] args) { } }

public class Rectangle { int top; int left; int width; int height; public void initialize(int top, int left) { this.top = top; this.left = left; width = 0; height = 0; } public void initialize(int top, int width, int height) { this.top = top; this.width = width; this.height = height; } public void initialize(int top) { this.top = top; left = 0; width = 0; height = 0; } public void initialize(int top, int left, int width, int height) { this.top = top; this.left = left; this.width = width; this.height = height; } public static void main(String[] args) { } }

Lets says that you did that and then tried calling initialize like this:

initialize(5,8,13);

which one would you be calling?

ya makes sense... is it also not possible with constructors as well? thanks

Constructors and methods can not have the same signatures. The signature is the name and the type of the parameters. Like you saw, 2 initialize methods with 3 int variables would not work, however you could have 1 with 2 ints and 1 with 3 ints; or 1 with 3 ints and one with 3 doubles.... or any number of combinations that you can think of.
