Question

Need to find out more optimized ways to code in Java.

Here is a very simple sample code

int index1 = line.indexOf(" ", word1.length() + 1);
if (!line.isEmpty() && index1 != -1) {
line = line.substring(word1.length(), index1).trim().toLowerCase();
}

or

if(!line.isEmpty() && line.indexOf(" ",word1.length()+1) != -1){
line = line.substring(word1.length(), index1).trim().toLowerCase();
}

What I noticed is the most of the times you have to decide between better code readability or perhaps more optimized code. Which one is better approach?

Answer 1

In all cases where performance increases are marginal or not completely justified, aim for

Readability
