What is the immediate next block wrapped in curly braces after the if block in Java? [duplicate]

Recently, I received a piece of code like this, but I don't understand what is the next block right after the if block?

for(byte i = 0; i < 5; i++) {
    P: {
        if(condition) {
            break P;
        }
        {// what is the syntax of this?
            System.out.println("Is else block? no!");
        }
    }
}

At first, I thought it was shorthand for else, but I read a lot of documentation on Oracle and when I run the test, even though the condition of if above is satisfied, the code inside that block also is still executed, so I know it's not else.

So in the end, what was that block?

Your answer solved my question, I would appreciate it.
