Hello,​

Global varriable which is defined after the class tag and before Method. so there are two type of Global variable

1.Instace global variable

public class GolbalVariable{
public String username;
public String password;
}

    Explanation : this is called as instance variable . so on instance method you can access directly . suppose if you want to access inside statioc method then create Object of class and access it . if method is static then code to access the variable,

    ClassObject obj=new ClassObject();//create class Object from static method
    username;//if username is static
    obj.username; // if username is instance

    2.static global variable.

    public class GolbalVariable{
    public static String username;
    public static String password;
    }

    Explanation : You can access directly with class Name

    ClassObject obj=new ClassObject();//create class Object from static method
    obj.username;//if username is static

    ​Hope this is helpful!

    Thank You!!
