Difference between string and StringBuffer in Java.

Strings, which are widely used in Java programming, are a sequence of characters. In Java programming language, strings are treated as objects. The Java platform provides the String class to create and manipulate strings.

Whereas, StringBuffer class is a thread-safe, mutable sequence of characters.

• A string buffer is like a String, but can be modified.
• It contains some particular sequence of characters, but the length and content of the sequence can be changed through certain method calls.
• They are safe for use by multiple threads.
• Every string buffer has a capacity.

Example

      sBuffer.append(" String Buffer");
      System.out.println(sBuffer);
   }
}
