What this means is that, once a String is created, it stays in the pool in memory until being garbage collected. Therefore, even after you’re done processing the string value (e.g., the password), it remains available in memory for an indeterminate period of time thereafter (again, until being garbage collected) which you have no real control over. • Therefore, anyone having access to a memory dump can potentially extract the sensitive data and exploit it. • In contrast, if you use a mutable object like a character array, for example, to store the value, you can set it to blank once you are done with it with confidence that it will no longer be retained in memory. • Theses were some java interview questions and answers • Code Decode Playlists • Most Asked Core Java Interview Questions and Answers : • Core Java frequently asked Interview ... • Advance Java Interview Questions and Answers : • Advance Java Interview Questions • Java 8 Interview Questions and Answers : • Java 8 Interview Questions(New Features) • Hibernate Interview Questions and Answers : • Hibernate Interview Questions Java • Spring Boot Interview Questions and Answers : • Advance Java Interview Questions • Angular Playlist : • Angular Course Introduction || Angular 8 • GIT : • GIT • Subscriber and Follow Code Decode • Subscriber Code Decode : https://www.youtube.com/c/CodeDecode?... • Linkedin : / codedecodeyoutube • Instagram : / codedecode25 • #JavaInterviewQuestionsandAnswers #JavaInterviewQuestions #Intellipaat #JavaInterview #CoreJavaInterviewQuestions #JavaInterviewQuestionsandAnswersForExperienced #JavaTutorial #JavaProgramming #JavaTutorialForBeginners
