Question

I have a pretty complex java class with over 60 small helper methods used for easy readability and understanding.Just wondering, do you think having these many methods in a class could affect performance in any way?

class MyClass() { 

    //Some static final variables 

    MyInnerClass m = loadAllVariables(); 

    private void update(){ 
    } 
    ... 
    //All 60 methods come here 
    .... 
    private MyInnerClass loadAllVariables() { 
        MyInnerClass m = new MyInnerClass();  
        //load all variables with pre-initialized values 
    } 

    private MyInnerClass() { 
        int a, b, c; //In reality, I have over 20 variables 
    }  
}

No. The number of methods in a method doesn’t matter much. Only the methods used are really loaded. If you have thousands of methods this is more likely to be a problem for you (the developer)

Keeping your code simple and clear is more likely to improve performance.
