How can Java call methods of other classes?

In order to call methods from other classes, you need to create an instance of that class and then use that object to call the method. The specific steps are as follows:

1. Import the package where other classes are located (if necessary).

import com.example.OtherClass;

1. Create instances of other classes.

OtherClass otherObject = new OtherClass();

1. Invoke methods of another class through an object.

otherObject.methodName();

When calling a method, it is possible to pass parameters to the method. For example, if a method accepts a string parameter, it can be called like this:

otherObject.methodName("Hello, World!");

You can choose to call static methods or instance methods from other classes based on the actual situation. If it is a static method, you do not need to create an instance object, you can directly call it using the class name.

OtherClass.staticMethod();
