//Runtime errors in java are UNCHECKED exception

​

//this means they do not need to be handled by a try-catch block or another way

try{

    //your code

}catch(Exception e){

    //What to do about the exception

}

​

//this also means we can ommit the throws statement in the method header

public static void main(String[] args) throws Exception{

    //your code

}
