.

Example:


class Solution{
    // private variable
    private String name;
}

public class Main {
    public static void main(String[] main){

        // create an object of TUF
        TUF d = new TUF();

        // access private variable and field from another class
        d.name = "Take You Forward";
    }
}

The above code will give us error :
Main.java:18: error: name has private access in TUF
        d.name = "Take You Forward";

How can we access private variables?

We can use getters and setters to access the private variables.

Example:


class Solution {
    private String name;

    // getter method
    public String getName() {
        return this.name;
    }
    // setter method
    public void setName(String name) {
        this.name= name;
    }
}
public class Main {
    public static void main(String[] main){
        TUF d = new TUF();

        // access the private variable using the getter and setter
        d.setName("Take You Forward");
        System.out.println(d.getName());
    }
}

In this way, we can access the private members, the setter method is used to assign values, and the getter method is used to access the variables.

Default :

If a class member doesn’t have any access modifier specified, then it’s treated with default access.
This means that method or attribute can be accessed only by classes in the same package.
Also, called a private package, which means that all members are visible within the same package but aren't accessible from other packages:
Keyword: no specified keyword.

Example:


package defaultPackage;
class Solution{
    void message(){
        System.out.println("This is a default");
    }
}

Protected:

If a class member is “protected” then it will be accessible only to the classes in the same package and to the subclasses.
Keyword: protected.

Example:


class Solution {
    // protected method
    protected void display() {
        System.out.println("Take You Forward!");
    }
}

class Student extends TUF {
    public static void main(String[] args) {

        // create an object of Student class
        Student s1 = new Student();
         // acc
