Both Java & Apex syntax are same.
1. if Method are Static then we can invoke method: Class_Name.MethodName();
2. If method are no-Static then:
2.1: Create instance of class
2.2: invoke method using object: Oob.MethodName();
Example:
=========================================================================================================
public class MyFirstClass{
public void doOperation1(){
// Enter statement here
}
public static void doOperation2(){
//Enter statement here
}
}
=========================================================================================================
Invoke Controller Method from Trigger
//To call doOperation1() method
MyFirstClass obj = new MyFirstClass();
obj.doOperation1();
//To call doOperation2() method - above i have mentioned, Static method can call directly using ClassName.Method_Name
MyFirstClass.doOperation2();
Please let me know if you find any issue & need more help.

You can create instance of class and call methods from trigger and you also call static methods of class without creating a instance of class and you can create method in Trigger also,
