Hi Yodha,

Yes, you can do that something like below:
public class MethodOverloading {
    public static Integer sum(Integer one, Integer two){
        return one+two;
    }
    
    public static Integer sum(Integer one, Integer two, Integer three){
        return one+two+three;
    }
    
    public static Integer sum(Integer one, Integer two, String str){
        System.debug(str);
        return one+two;
    }
}

The above methods can be called like below:
Integer sum1 = MethodOverloading.sum(10, 15);
Integer sum2 = MethodOverloading.sum(10, 15, 17);
Integer sum3 = MethodOverloading.sum(10, 15, 'Sum Calculated');
System.debug(sum1);
System.debug(sum2);
System.debug(sum3);

Please mark this as best answer if this answers your query.
