There are two ways to check if two Strings are equal. You can use the==operator or theequals()method. When you use the==operator, it checks for the value ofStringas well as the object reference. Often in Java programming you want to check only for the equality of theStringvalue. In ...
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...
