Ok simple example
You make one class that name is : Demo
class Demo{
}
Inner you make a constructer, that is what you call if you need it… look below
class Demo{
public Demo(int num, String str)
{
int num;
String str = "This is a parameterized constructor with number ";
System.out.println(str + num);
}
}
You can make more of them for example an empty constructer or with a defined value
Now you can call your class with that constructer something like that :
public static void main(String args[]){
String strrrrr = "This is your value of variable int"
int i = 99;
Demo demo = new Demo(strrrrr, i);
}
So you can see that you console gives you message with your variable String strrrrr and int i
I hope I could help you 😉
