Java Class Attributes

In the previous example, we created a variable in a Java class MyClass and it is known as attribute of the class. In other words, class attributes are variables within a class. The class attributes are also called as fields.

Example

In the below example, we create class attributes “text” and “x”:

public class MyClass {
       String text = "Hello World!";
       int x = 100;
}

 

Accessing Attributes

The class attributes can be accessed using the dot syntax(.)

Example

In the below example, we create a  object “myObj”. We print the class attributes using the dot syntax:

public class MyClass {
       String text = "Hello World!";
       int x = 100;
      
       public static void main(String args[]){
              MyClass myObj = new MyClass();
              System.out.println(myObj.text);
              System.out.println(myObj.x);
       }
}

Output

Hello World!
100

Modify Attributes

The class attributes can also be modified.

Example

In the below example, we override the value of class attributes “text” and “x” in the main class:

public class MyClass {
       String text = "Hello World!";
       int x = 100;
      
       public static void main(String args[]){
              MyClass myObj = new MyClass();
              myObj.text = "Friends";
              myObj.x = 50;
              System.out.println(myObj.text);
              System.out.println(myObj.x);
       }
}

Output

Friends
50
