How to avoid recursive trigger calls in Salesforce?

Here is the code-

Apex class:-

public Class checkRecursive {
    private static boolean run = true;
    public static boolean runOnce(){
        if(run){
            run=false;
            return true;
        } else{
            return run;
        }
    }
}

Trigger -

trigger updateTrigger on anyObject(after update) {
    if(checkRecursive.runOnce())
    {
        //write your code here
    }
}

Thanks.
