global variabe in Java?

[glwong]

How can I make a variable declared in one class
visible in another class?

Thanks,
Greg

You can declare it to be public, but this is bad programming practice. The best way to do this is to create an accessor and mutator function.

class NameHolder{

  public String getName(){
    return name;
  }

  public setName(String name){
    this.name = name;
  }


  private String name;
}

Then call getName(accessor) and setName(mutator) to access your variable.

Something along those lines is your best bet. Hope that helped. MYenigmaSELF:-9

Also, if you want it to be truly global then just declare it to be static:

class NameHolder{

  public static String getName(){
    return name;
  }

  public static setName(String name){
    this.name = name;
  }


  private static String name;
}

Then whenever you want to modify this "global" name just call NameHolder.setName(String), etc... I'm pretty sure this should work. I get my languages confused sometimes. Good Luck MYenigmaSELF:-9

just declare them PUBLIC STATIC

for example:

import java.awt.*;

public class YOURCLASS {

public static int NUMBER;
