java access variable from another class

Comment

To access a variable from another class in Java, the variable must be declared as public or accessed via a getter method.
// Class A
public class A {
    public int value = 10;
}

// Class B
public class B {
    public static void main(String[] args) {
        A obj = new A();
        System.out.println(obj.value); // Access public variable
    }
}
Example: Getter Method// Class A
public class A {
    private int value = 10;
    public int getValue() {
        return value;
    }
}

// Class B
public class B {
    public static void main(String[] args) {
        A obj = new A();
        System.out.println(obj.getValue()); // Access via getter
    }
}
