What is the difference between string and stringbuffer in Java?
I was enrolled in a Java learning online program and I have a doubt regarding one topic. My doubt is what is the basic difference between the string and stringbuffer in the whole context of Java programming?
In the context of Java learning online you were taught that the difference between string and stringbuffer in Java is that both are used for manipulation of the strings, however, there are various minute differences between them. Here are the differences following:-
In the context of Java programming the values of the strings cannot be changed if you as a user created it once. If you try to modify or change the string then you will get a new string automatically. On the other hand, stringbuffer is changeable. It means you as a user can change the string even without creating new strings.
In the context of synchronization, the strings are thread-safe. It is so because they are immutable. On the other hand, stringbuffer is mainly designed for the thread-safe and its methods are also on the safer side. However, it may have a performance cost.
