Pls help, urgent... I'm giving out all my duke dollars...

Question

Hi, thanks for reading...
My problem is I need to assignment some value into an variable when the "main" program start and I want the data inside this variable visible to all the class to use (by using the getter methods to get the value),
For example: From the code below (the clsMain), it is possible to get the same value assigned into the "strGrandChildName" variable in the "main" program inside the "clsChild" class? Any idea how to make this thing work? pls help me... with some sample code... i really appreciate any help you guys can give.
Thank You,
Best Regards.
public class clsGrandChild {
private String strGrandChildName = "";
public void mtd_setGrandChildName(String strIn) {
strGrandChildName = strIn;
public String mtd_getGrandChildName() {
return strGrandChildName;
public class clsChild {
private String strChildName = "";
public void mtd_setChildName(String strIn) {
strChildName = strIn;
public String mtd_getChildName() {
return strChildName;
public String mtd_GrandChildName() {
// can i get the same value of strGrandChildName assigned in the main frm here?
public class clsMain extends clsGrandChild {
public static void main(String[] args) {
mtd_setGrandChildName("grand child name");
clsChild objChild = new clsChild();
objChild.mtd_GrandChildName();

public class clsGrandChild {
private String strGrandChildName = "";
public void mtd_setGrandChildName(String strIn) {
strGrandChildName = strIn;
public String mtd_getGrandChildName() {
return strGrandChildName;
public class clsChild {
private String strChildName = "";
public void mtd_setChildName(String strIn) {
strChildName = strIn;
public String mtd_getChildName() {
return strChildName;
public String mtd_GrandChildName() {
// can i get the same value of
alue of strGrandChildName assigned in the main frm
here?
public class clsMain extends clsGrandChild {
public static void main(String[] args) {
mtd_setGrandChildName("grand child name");mtd_setGrandChildName("grand child name") shouldn't be called here, it should be called after the
clsChild object has been created

clsChild objChild = new clsChild();objChild. mtd_setGrandChildName("grand child name");
objChild.mtd_GrandChildName();
If to access the variable strGrandChildName before the instanciation of clsChild object is what you needed, then you will need to set the string strGrandChildName as static and also setter method
needs to be static too.
private static String strChildName = "";
public static void mtd_setGrandChildName(String strIn) {
strGrandChildName = strIn;
by doing it this way, the static variables will be created when main thread starts.
