why the i m getting the error

Question

public class Axis {
public static void main(String[]args) {
Fire high = new Fire();
Fire.setH(23);
int j = Fire.getH();
System.out.print(j);
}
}
class Fire {
private static int h;
public void setH(int y) {
this.h=y;
}
public static int getH() {
return h;
}
}

ERROR: non static method setH(23)cannot be refrenced through static context.

Answer 1

Good job. Because you made setH static method , and h is static , then you can't use (this )
* this is a non static variable

To solve this problem and make the program run well, instead of it just write (h=y;) in setH method

Answer 2

public class Vehicle {
private String color;

// Getter
public String getColor() {
return color;
}

// Setter
public void setColor(String c) {
this.color = c;
}
}
//Main
class Program {
public static void main(String[ ] args) {
Vehicle v1 = new Vehicle();
v1.setColor("Red");
System.out.println(v1.getColor());
}
}
//Order out of Khaos ...👍

Answer 3

high.setH(23); instead of
Fire.setH(23);

EDIT:
A non-static class (being instantiated by You anyway ) can be accessed by instance -
my first line.

A static class is reachable by referrence only-
my second line.

I have provided link thnx for your response.

Answer 6

use public static void setH()
or call with the object not with class directly

Answer 7

If you want to call with the object you should remove static word from all methods in class Fire. And call like (high.setH(3), high. getH())

Otherwise , you should make all methods static. And call like (Fire. setH(4), Fire. getH())

Answer 8

shobhit , could write here the new code you have just edited?

Answer 9

The above code that you wrote in first time (your question) can be solved by just writing (high. setH(23) ) instead of (Fire. setH(23))
