even after performing security checks, would be safe.The untrustworthy caller method still has the reference and can change theStringbetween integrity checks. Thus making our query prone to SQL injections in this case. So mutableStringscould lead to degradation of security...
Furthermore, the immutability of String has broader implications beyond thread safety. Strings are commonly used as parameters in various Java classes, such as network connections or file operations. If String were mutable, it would pose a serious security threat. For instance, if a network connect...
HashSet<String>set=newHashSet<String>();set.add(newString("a"));set.add(newString("b"));set.add(newString("c"));for(Stringa:set)a.value="a"; In this example, ifStringis mutable, it's value can be changed which would violate the design of set (set contains unduplicated elements...

If a string is mutable, changing the string with one reference will lead to the wrong value for the other references. 2. Caching Hashcode The hashcode of a string is frequently used in Java. For example, in a HashMap or HashSet. Being immutable guarantees that hashcode will always be the...

You can follow some strategies to define immutable objects in Java Concurrency. Let’s see them below: You shouldn’t use the methods that could change object fields. It would help if you made all object fields private and final. When instance fields include references to mutable objects, you...
