Design Strings are created in a special memory area in java heap known as "String Intern pool". While you creating new String (Not in the case of using String() constructor or any other String functions which internally use the String() constructor for creating a new String object; String(...
1. Requirement of String Pool String pool (String intern pool) is a special storage area inMethod Area. When a string is created and if the string already exists in the pool, the reference of the existing string will be returned, instead of creating a new object. The following code will ...
stuff like String apple = "apple"; where as the String constant pool may refer to the constant string objects like those using the keyword final, although to receive a question with tricky semantics like that would annoy me if I got it in an interview ...
This concept can be safely achieved without any data corruption as String is immutable in Java. Example class StringConstantPool1{ public static void main(String args[]){ String s1="java"; String s2="java"; String s3="java"; String s4="java"; System.out.println(s1==s2); System.out....
It happens because they are located at different locations in a heap. Besides being two objects, there are no significant differences in both objects. If we use the concept of String Interning, we only create a single object let us assume it asstrObj, and now it contains the content of th...
The Java strings constant pool is the sum total available memory for Java to use declaring active strings. See how creating a new string uses the...

Java has a concept called “string interning,” where strings that are created using string literals are stored in a common pool. This can optimize memory usage and improve equality checks for these strings. String s1 = "hello"; String s2 = "hello"; boolean areEqual = s1 == s2; // tr...
"Java Tutorial", the string may be taken from the string constant pool in Java heap memory if an identical string is available. This concept is known as string interning, where string literals are stored in a pool to optimize memory usage and enhance performance. In this way, string ...
method. Comparison using “==” is called shallow comparison because of == returns true, if the variable reference points to the same object in memory. Comparison using equals() method is called deep comparison because it will compare attribute values. Let’s understand this concept by java ...
