what is the difference between heep & pool in Strings?
posted 14 years ago
If you use the special syntaxes for String the JVM will try to optimize by re-using Strings that already exist in the Pool. This is more efficient if there are duplicate strings. The special syntaxes include String s = "asfasfasd"; //directly naming String x = s + "sdfsd"; // concatenation If you make a String using the "new" operator an object will be created on the heap (where most objects live) even if there is a string object in the pool which matches it. See this thread from yesterday. http://www.javaranch.com/ubb/Forum33/HTML/003680.html
