as we know a static method could access static data and
static method only. then how could main method call the
object of aclass which is not static and other non static data
Answer / ramya
though main method is static, it can access non-static
(instance) variabels or methods by creating an instance of
the class in which the variables and methods are..
Example:
class LessonTwoB {
String text = "I'm a Simple Program";
static String text2 = "I'm static text";
String getText(){
return text;
}
String getStaticText(){
return text2;
}
public static void main(String[] args){
LessonTwoB progInstance = new LessonTwoB();
String retrievedText = progInstance.getText();
String retrievedStaticText =
progInstance.getStaticText();
System.out.println(retrievedText);
System.out.println(retrievedStaticText);
}
}
