UseIndexOfChar

UseIndexOfChar

Use String.indexOf(char) when checking for the index of a single character; it executes faster.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.strings.UseIndexOfCharRule
Example(s):



String s = "hello world";
  // avoid this
if (s.indexOf("d") {}
  // instead do this
if (s.indexOf('d') {}
