在以下情况下使用StringBuilder或String？

Question

String address=null;
String body = "";
String date = "";

for(int i = 0; somecondition; i++)
{    
    body = cursor.getBody(i);
   //and so on all strings get changed

//REST OF THE CODE
}

This loops for arround 500 times so what should I use?

Answer 1

Given that nothing changes in the String you are just reassigning it, use a String. StringBuilder is used when you want to build up a String in pieces.

Answer 2

Since you're just assigning some string to the variable, just use String instead of StringBuilder. StringBuilder as its name suggest, is used for building a new string where concatenation or manipulation is desired.

Answer 3

Your example doesn't build any String, just going assign values. In that case you can use String
