Hi Otávio, while I personally like using chars instead of Strings where applicable, I would assume these constant replacements are all cases where the JIT will be quick to inline and eliminate the overhead. So the benefit, if any, would be in interpreted code. Testing these assumptions with a simple but representative JMH[1] microbenchmark[2]: Benchmark Mode Samples Mean Mean error Units o.s.MyBenchmark.indexOfChar thrpt 20 32290.764 359.347 ops/ms o.s.MyBenchmark.indexOfString thrpt 20 32353.865 398.929 ops/ms o.s.MyBenchmark.lastIndexOfChar thrpt 20 32444.428 462.630 ops/ms o.s.MyBenchmark.lastIndexOfString thrpt 20 32001.738 388.791 ops/ms So no real difference, as suspected. Running with -Xint: Benchmark Mode Samples Mean Mean error Units o.s.MyBenchmark.indexOfChar thrpt 20 3170.130 108.933 ops/ms o.s.MyBenchmark.indexOfString thrpt 20 3119.518 44.703 ops/ms o.s.MyBenchmark.lastIndexOfChar thrpt 20 3281.374 25.589 ops/ms o.s.MyBenchmark.lastIndexOfString thrpt 20 3154.710 45.224 ops/ms Not much - if anything - here either. I think more evidence that this would have some actual benefit is warranted. /Claes [1] http://openjdk.java.net/projects/code-tools/jmh/ [2] package org.sample; import org.openjdk.jmh.annotations.*; import java.util.Random; @State(Scope.Thread) public class MyBenchmark { /* * Generate a lot of randomly generated strings of various sizes */ static int NUM = 100000; static int MAX_SIZE = 1000; static String[] STRINGS = new String[NUM]; static { Random r = new Random(); for (int i = 0; i < NUM; i++) { StringBuilder sb = new StringBuilder(r.nextInt(MAX_SIZE) + 1); for (int j = 0; j < sb.capacity(); j++) { sb.append((char)(r.nextInt(70) + '0')); } STRINGS[i] = sb.toString(); } } private int i = 0; @GenerateMicroBenchmark public int indexOfString() { if (i >= NUM) { i = 0; } return STRINGS[i++].indexOf("6"); } @GenerateMicroBenchmark public int lastIndexOfString() { if (i >= NUM) { i = 0; } return STRINGS[i++].indexOf("6"); } @GenerateMicroBenchmark public int indexOfChar() { if (i >= NUM) { i = 0; } return STRINGS[i++].indexOf('6'); } @GenerateMicroBenchmark public int lastIndexOfChar() { if (i >= NUM) { i = 0; } return STRINGS[i++].indexOf('6'); } } On 2014-04-26 12:56, Otávio Gonçalves de Santana wrote:
When a String has length just one, could be replaced by equivalent character literals, gaining some performance enhancement.
