Nested loops
Now, we’ll cover the fundamental concepts, practical optimization strategies, and technical intricacies involved in effectively optimizing nested loops in Java applications. We will tackle the concept of nested loops, as they relate to high-performance Java applications, in the following sections:
- Introduction to nested loops
- Loop fusion in nested loops
- Parallelizing nested loops
- Nested loop vectorization
It is important to understand when to use nested loops and, when we do, how to implement them in the most optimal method.
Introduction to nested loops
A nested loop is when one loop is located inside another. This creates a complex iteration scenario. Here is the syntax for a simple nested loop:
for (int i = 0; i < 10; i++) { // Outer loop
for (int j = 0; j < 10; j++) { // Inner loop
&...
