can we write multiple trigger on an object salesforce

public class TestObjectTriggerHelper{

	public TestObjectTriggerHelper(){
		// constructor logic
	}
	public void beforeInsert(List<TestObject__c> newLst, List<TestObject__c> oldLst){
		// before insert action code block
		// method_1(); By calling different methods in other classes, you can change the order of execution also
		// method_2();
	}
	public void beforeUpdate(List<TestObject__c> newLst, List<TestObject__c> oldLst){
		// before update action code block
		// method_1();
		// method_2();
	}

	........
	...

	public void afterInsert(List<TestObject__c> newLst, List<TestObject__c> oldLst){
		// after insert action code block
		// method_1();
		// method_2();
	}
	public void afterUpdate(List<TestObject__c> newLst, List<TestObject__c> oldLst){
		// after update action code block
		// method_1();
		// method_2();
	}
	........
	....
}

trigger TestObjectTrigger on TestObject__c (before insert, after insert, before update, after update,...) {
	
	TestObjectTriggerHelper helper = new TestObjectTriggerHelper();

   if(trigger.isBefore) {

   		if(trigger.isInsert) {   			
   			helper.beforeInsert(trigger.new, trigger.old);
   		}
   		if(trigger.isUpdate) {
   			
   			helper.beforeUpdate(trigger.new, trigger.old);
   		}
   		....
   		..
   		.
   }
   if(trigger.isAfter) {

   		if(trigger.isInsert) {
   			
   			helper.afterInsert(trigger.new, trigger.old);
   		}
   		if(trigger.isUpdate) {
   			
   			helper.afterUpdate(trigger.new, trigger.old);
   		}
   		....
   		..
   		.
   }
