按照注释在下面的代码中插入缺失的部分：

// Create a MyClass class public class MyClass { int x; // Create a class attribute x // Create a class constructor for the MyClass class public MyClass() { x = 5; // Set the initial value for the class attribute x to 5 } public static void main(String[] args) { // Create an myObj object of class MyClass (This will call the constructor) MyClass myObj = new MyClass(); // Print the value of x System.out.println(myObj.x); } }
