How to stop recursive trigger in Salesforce?

To avoid recursive triggers you can create a class with a static Boolean variable with default value true. In the trigger, before executing your code keep a check that the variable is true or not. Once you check to make the variable false.

Example:

Apex Code:

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

Trigger Code:

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