  I am sorry I dont know VB you might know VB i guess . I can give you the structure in Java. so you can refer it and model from it class vehicle { // all of the public methods will be available in classes car and lorry private int CC ; private int BHP; public int getCC() { return this.CC ; } public void setCC(int cc) { this.CC = cc; } public int getBHP() { return this.BHP ; } public void setBHP(int bhp) { this.BHP = bhp; } } class car extends vehicle { // some variables and functions } class lorry extends vehicle { private int MaxTransWeight ; public int transferrableWeight ( ) { return MaxTransWeight ; } public void setTransferrableWeight (int weight ) { MaxTransWeight = weight ; } }
