what is meant by string pooling?
Answer Posted / indrajit yadav
A string pool is a collection of references to String
objects."String Literal Pool" still live on the heap memory,
but they have references to them from the String Literal Pool.
See the below example:
public class Program {
public static void main(String args[]){
//String literal will store in String pool
String s1="Indrajit";//case 1
String s2="Indrajit";//case 2
//In case 1, iteral s1 is created newly and kept in the
pool. But in case 2, literal s2 refer the s1, it will not
create new one instead
//String object
String s = new String("hi");
String ss = new String ("hi");
if (s1==s2){
System.out.print("equal");//print equal
}
/*
if(s==ss){
System.out.print("Reference are not equal");//no ouptput
}
*/
}
}
