Question

I was going through some Java tutorials in a book and ran across code like this:

private void theMethod( MyObject table )
{
  SomeObject item1 = table.add(0,0,0,"Item 1");
  {
    item1.setWhatever = false;
    item1.setSomething = 15;
  }

  // More code here...
}

What is the purpose of the braces following the variable definition?

Answer 1

I use this braces sometimes in group when I’m using a lot of local variables. This way, they are out of scope and I can create variables with the same name.

I can’t find immediately a good example, but I mean something like this:

/* Code block 0 */
{
    int localStuff = 9;
    boolean submit = false;
    // Do some IO, or whatever
}
/* Code block 1 */
{
    int localStuff = 4;
    boolean submit = false;
    // Do some IO, or whatever
}

/* Code block 2 */
{
    int localStuff = -1;
    boolean submit = true;
    // Do some IO, or whatever
}
