How to format selected java code in sublime text .txt file

Is there any extension or technique for formatting java code in sublime text?

For example,

I have this code:

    static void test() 
{
        Pair<Integer, Integer>[] intPairArr = new Pair<Integer, Integer>[10]; // error
         addElements(intPairArr);
        Pair<Integer, Integer> pair = intPairArr[1];
           Integer i = pair.getFirst();
        pair.setSecond(i);
        }

I want this formatted code:

static void test() {
    Pair<Integer, Integer>[] intPairArr = new Pair<Integer, Integer>[10]; // error
    addElements(intPairArr);
    Pair<Integer, Integer> pair = intPairArr[1];
    Integer i = pair.getFirst();
    pair.setSecond(i);
}

I don't want to use an IDE for formatting code in a sublime text .txt file. Basically I want to select a snippet Java code in .txt file and format it properly.

1. I tried CodeFormatter plugin for Sublime Text.I get the following
   error:

   Formatter for this type(plain text) not found
   

2. I tried Edit > Line > Reindent but this technique is waste of time.

3. I tried Sublime​AStyle​Formatter plugin for Sublime
   Text, as well.When I select my code and press Ctrl+K
   for formatting my current selection, it doesn't work.
