Replaces String concatenation with StringBuilder #98

Open

joimxjtuse commented Dec 18, 2018

in practice, i don't always use StringBuilder replace str1 + str2.

str1 + str2, JVM may do this optimize for us (https://stackoverflow.com/questions/1532461/stringbuilder-vs-string-concatenation-in-tostring-in-java), this looks short;
str1+str2+str3+...+strn, StringBuilder looks more clean;
while face for (String s : arrs), always use StringBuilder.append() to implement.
