package com.lab126.util.framebuffer;

public class FrameBufferException extends RuntimeException{
    
    private static final long serialVersionUID = 1L;
    private int errorCode = 0;

    public FrameBufferException() {
        super();
   }

    public FrameBufferException(String msg) {
        super(msg);
    }

    public FrameBufferException(Throwable t) {
        super(t);
    }

    public FrameBufferException(String msg, Throwable t) {
        super(msg, t);
    }

    public int getErrorCode() {
        return this.errorCode;
    }
}

I think this version is more readable
