STRCON.LOOP
Using string concatenation in a loop wastes time and memory. Use StringBuffer instead.
Example 1
Copy
public String test1(int n, String x) {
String res = "";
for (int i = 0; i < n; i++) {
res+=x;
}
return res;
}
// fixed code
public String test2(int n, String x) {
StringBuffer res = new StringBuffer();
for (int i = 0; i < n; i++) {
res.append(x);
}
return res.toString();
}
