Hi,
Please can anyone help me  with how to merge these two codes into one?
I wrote the following  codes separately  for same the custom object, and I dont know how to consolidate them into one code
. Any help will be appreciated !

1st Code: 
trigger SetContactOnAssetRecord on Assets_Check_in_Checkout__c (before update,before insert) {
    set<string>Netid = new Set<string>();
    for (Assets_Check_in_Checkout__c a  : Trigger.new){
       Netid.add(a.GU_Net_ID__c) ;
        
    }
    List<Contact> ContactList = [ select id, GU_Net_ID__c from Contact where GU_Net_ID__c IN :Netid ];
    Map<string,Contact> netidToContactMap= new Map <string,Contact>();
    
    for (Contact c : ContactList){
        
      netidToContactMap.put(c.GU_Net_ID__c,c);  
        
    }
    for(Assets_Check_in_Checkout__c chk : Trigger.new ){
        if(chk.GU_Net_ID__c != null && netidToContactMap.containsKey(chk.GU_Net_ID__c) ){
            system.debug('Contact id:' + netidToContactMap.get(chk.GU_Net_ID__c).id);
            chk.Loaner__c = netidToContactMap.get(chk.GU_Net_ID__c).id;
        }
        else
        {
           chk.addError('Netid not exist in Salesforce');
 
        }
    }
    
}


2nd Code:

trigger UpdateStatus on Assets_Check_in_Checkout__c (after insert, after update) {
 // Create a list of assetids
    List<Id> assetIds = New List<ID>();
    set<id> assetName = new set<id>();
    Map<id,id> Assetid = new Map<id,id>();
    List<Asset> LAsset = new List<Asset>();
    
    if(Trigger.isInsert){
        for(Assets_Check_in_Checkout__c AssID : Trigger.new){
        if(!string.isBlank(assid.Asset_Name__c))
        {
            Assetid.put(assID.id, assid.Asset_Name__c);
        }
    }
    }
    
    if(Trigger.isUpdate)
    {
    for(Assets_Check_in_Checkout__c AssID : Trigger.new){
        
        if(!string.isblank(assid.Asset_Name__c) && Trigger.oldMap.get(AssID.id).Status__c != Trigger.newMap.get(AssID.id).Status__c)
        {
            Assetid.put(assID.id, assid.Asset_Name__c);
            assetName.add(assid.Asset_Name__c);
        }
    }
    }
    
    for(Asset a: [select id, status,(select name, status__c from Assets_Check_in_Checkout__r where id IN:Assetid.keySet()) from Asset where id IN: AssetId.values()]){
        
        
        for(Assets_Check_in_Checkout__c ACC : a.Assets_Check_in_Checkout__r)
        {
            Asset a1 = new Asset();
            if(acc.status__C == 'Check-in')
            {
                a1.Status = 'Available';
                a1.id = a.id;
                LAsset.add(a1);
            }
            else if(acc.status__c == 'Checkout')
            {
                a1.Status = 'Not Available';
                a1.id = a.id;
                LAsset.add(a1);
            }
        }
        
       
    }
    
    Update LAsset;
}
