๐ Welcome to Day 5 of the 10-Day Java Challenge on PureJava! ๐
Today's challenge takes a deep dive into the behavior of StringBuilder in multi-threaded environments. StringBuilder is widely used in Java for its efficiency in string manipulation, but what happens when it's used in a multi-threaded context? ๐ค
Challenge 5:
StringBuilder sb = new StringBuilder("Java");
sb.append(" Programming");
System.out.println(sb.toString());
๐ค Question: What will be the output of this code in a multi-threaded environment? Will the result be what you expect, or could there be some unexpected behavior? Think carefully about how StringBuilder works and its implications when multiple threads are involved.
๐ Key Concept: StringBuilder is not thread-safe, which can lead to issues when used in multi-threaded applications. Understanding this is crucial for writing efficient and error-free Java code.
