Exploring Encapsulation in Java

Report a typo

In the context of Java, consider the following code snippet:


 public class Person {
     private String name;
     private int age;

     public String getName() {
         return this.name;
     }

     public void setName(String name) {
         this.name = name;
     }

     public int getAge() {
         return this.age;
     }

     public void setAge(int age) {
         if (age > 0) {
             this.age = age;
         }
     }
}

Based on this Java code and the concept of access control and encapsulation, which of the following statements are true?

Select one or more options from the list

The 'setAge()' method is an example of a setter with validation to prevent setting invalid age.

The visibility of 'getAge()' and 'setAge()' should be private.

We modified the 'age' field directly without using setter, which violates the encapsulation principle.

The 'setName()' method could have been left out because it's not standard Java practice.

The principle of encapsulation is maintained by making the 'name' and 'age' fields private and accessing them through public methods.
