What is the purpose of using separate {} block in a function?

I saw a code in a project and there was a { } block inside of a method without any specifier etc.

Working code was something like this:

public void someMethod(params) {

    //some code1
    //some code1
    
    {
        //some code2
        //some code2
    }
    //some code3
    //some code3
}

As you see some code2 is in a separate block.

What is the reason for doing this? Is it making a functional difference or just a coding standard?

What was the actual code? – tgdavies Dec 22 '20 at 13:28
You'd have to ask the author why he wrote it. However, braces are how lexical scope is defined (a variable defined in the block goes out of scope at the closing brace), so maybe that's the reason. – a guest Dec 22 '20 at 13:28

I don't know about Java specifically, but it's probably a scope block. – TARN4T1ON Dec 22 '20 at 13:28

Those create a separate scope. Variables inside it are not visible to the outer scope. – MC Emperor Dec 22 '20 at 13:30
