Anonymous code blocks in Java
java
Solution
They restrict variable scope.
public void foo()
{
{
int i = 10;
}
System.out.println(i); // Won't compile.
}
In practice, though, if you find yourself using such a code block that's probably a sign that you want to refactor that block out to a method.
Problem
Are there any practical uses of anonymous code blocks in Java? ``` public static void main(String[] args) { // in { // out } } ``` Please note that this is not about named blocks, i.e. ``` name: { if ( /* something */ ) break name; } ``` .
