How do you call a class in Java?

To call a class in Java, you need to create an object. The specific steps are as follows:

1. Import the package where the class is located: Before using it, you need to import the package where the class is located, which can be done using the import statement, for example: import com.example.MyClass;
2. Creating objects: use the “new” keyword and constructor method to instantiate a class object, for example: MyClass myObject = new MyClass();
3. Invoking methods and accessing properties of a class: To invoke methods and access properties of a class, use the object name followed by the dot operator, such as myObject.methodName(); or myObject.propertyName;

Here is the full example code:

import com.example.MyClass;

public class Main {
    public static void main(String[] args) {
        // 创建对象
        MyClass myObject = new MyClass();

        // 调用类的方法
        myObject.methodName();

        // 访问类的属性
        myObject.propertyName = 10;
    }
}
