Question

Which of the following creates the string of the numbers from 1 to 1000 most efficiently?
A) String s; 
for (int i = 1; i <= 1000; i++)
S += i;
B) StringBuilder sb = new StringBuilder(10);
 for (int i = 1; i <= 1000; i++)
Sb)append(i);
String s = new String(sb);
C) StringBuilder sb = new StringBuilder(3000); 
for (int i = 1; i <= 1000; i++)
Sb)append(i);
