In java, the comparison of two string objects using "==" always results in a reference comparison. Therefore string comparison is always done using String.equals(), the same concept of literal pools applies java though. Sample this: String str1="xyz"; Object obj1="xyz"; String str2=new ...
public class UniqueString { // 'removable = false' means the string would be added to the global string pool // which would stay in memory in the rest of the whole execution period. public static string Intern(string str, bool removable = true) // Why return a ref rather than a bool?
String interning Folks, On a hunch, I just tried adding to my hand-written JAXB binding a java type adapter which calls intern() on each String as it is unmarshalled on to the object model. This reduced the heap size of the resulting object graph from 22meg to 8meg. It also increased...

Using String Interning in Java In the below example, we see how we can use the method of String Interning using theintern(). We create five String variables. The first String variablestris created usingnew String(), and the string is passed in the constructor. Next, we create another strin...
在Java中,显式声明的字符串由JVM实现,因此相同String的后续声明会产生两个指向同一String实例的指针,而不是两个单独的(但相同的)字符串. 例如: public String baz() { String a = "astring"; return a; } public String bar() { String b = "astring" return b; } public void main() { String a...
Java stores the string contants appearing in the source code in a pool. In other words when you have a code like:
Strings and characters in Clojure are the same as in Java. The string literals are implicitly interned. Interning is a way of storing only the unique values in the heap and sharing the reference everywhere it is required. Depending on the JVM vendor and the version of Java you use,...
