Something look wrong in this code

Question

This my code , whenever i need to change x value of object ofdr this error pops up.

import java.util.Scanner;
public class Class {

Class (double x,double b,double c) {

}

public static void main(String[] args) {
double x2;
double b2;
double c2, d2;
Scanner xt = new Scanner(System.in);
System.out.println("x ادخل قيمة ");
x2 = xt.nextInt();
Class ofdr = new Class(0,0,0);
x.ofdr = 5;

}

}

The error is like this

javac Class.java
Class.java:21: error: cannot find s
ymbol
x.ofdr = 5;
^
symbol: variable x
location: class Class
1 error

Process exited with code: 1

Answer 1

x is neither an object nor it is declared in your class. That's why the error "Cannot find symbol" x in your class named Class.

If you just want to change the value then try something like this..for now..

public class Class {
double x; // declaring instance variable x.

public static void main (String [] args) {

Class obj = new Class (); // creating a Class object named obj.

obj.x = 5; // assigning value to obj's instance variable x.

System.out.println (obj.x);
}
}

Later you might want to take a look into getters and setters.

Answer 4

1, you put double inside class arguments, but when you assign put integer
2, try ofdr.x=5.0;
