Can the instance variables of one class be used in another class?

Question

Is there anyway to do this depending on different access specifiers or some other way perhaps? Please help me.

Answer 1

Its depends on access specifiers ..

Public variable : Able to access from anywhere in the program.

Private variables: only accessible within the declared class..

Answer 4

or you can provide a reference

public class A {
private int[] arr2 = {5,6,7,8};

int[] getArr() { return arr2; }
}
public class Program {
public static void main(String[] args) {
var objA = new A();
int[] arr1 = objA.getArr();

System.out.println( arr1[0] ); // 5
}
}
