Efficient Java: String Concatenation

This repository contains a Java example comparing different methods of string concatenation to evaluate their performance.

Included

• Concatenation using String (+=)
• Concatenation using StringBuilder
• (Optionally) Concatenation using StringBuffer

The goal is to demonstrate which method is more efficient when building large strings inside a loop.

How to Run

Compile and run the Java files in the cadenas folder using your IDE or the command line:

javac ConcatenacionString.java
javac ConcatenacionStringBuilder.java
java ConcatenacionString
java ConcatenacionStringBuilder
