+# Java Tutorial: Creating Our Own Java Class
+### Writing a Custom Class : 
+- Syntax of a custom class :
+
+```
+class <class_name>{  
+    field;  
+    method;  
+}  
+```
+
+- Example :
+
+```
+public class Employee {
+	int id;			// Attribute 1
+	String name;		// Attribute 2
+}
+```
+
+**Note:** The first letter of a class should always be capital.
+
+- Any real-world object        = Properties + Behavior
+- Object in OOPs               = Attributes + Methods
+
+### A Class with Methods : 
+- We can add methods to our class Employee as follows:
+
+```
+/*
+public class Employee {
+	public int id;
+	public String name;
+
+	public int getSalary(){
+		//code
+		}
+	public void getDetails(){
+		//code
+		}
+	};
+*/
+```
+ 
+### Code as Described in the Video
+
+```
+class Employee{
+    int id;
+    int salary;
+    String name;
+    public void printDetails(){
+        System.out.println("My id is " + id);
+        System.out.println("and my name is "+ name);
+    }
+
+    public int getSalary(){
+        return salary;
+    }
+}
+
+public class cwh_38_custom_class {
+    public static void main(String[] args) {
+        System.out.println("This is our custom class");
+        Employee harry = new Employee(); // Instantiating a new Employee Object
+        Employee john = new Employee(); // Instantiating a new Employee Object
+
+        // Setting Attributes for Harry
+        harry.id = 12;
+        harry.salary = 34;
+        harry.name = "CodeWithHarry";
+
+        // Setting Attributes for John
+        john.id = 17;
+        john.salary = 12;
+        john.name = "John Khandelwal";
+
+        // Printing the Attributes
+        harry.printDetails();
+        john.printDetails();
+        int salary = john.getSalary();
+        System.out.println(salary);
+        // System.out.println(harry.id);
+        // System.out.println(harry.name);
+    }
+}
+```
