What does Static {} mean in the Java Syntax?

Question

I came across this Java code:

static {
    String aux = \"value\";
    try {
        // some code here
    } catch (Exception e) { }
    String UUID_prefix =         


        

Answer 1

This is a static initializer block. You must have found it in a class's body outside of any method. The static init block runs only once for each class, at classload time.
