Java StringBuffer class.

Java 8 Object Oriented Programming Programming

The java.lang.StringBuffer class is a thread-safe, mutable sequence of characters. Following are the important points about StringBuffer −

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

Live Demo

import java.lang.*;
public class StringBufferDemo {
   public static void main(String[] args) {
      StringBuffer buff = new StringBuffer("tuts ");
      System.out.println("buffer = " + buff);

      // appends the boolean argument as string to the string buffer
      buff.append(true);

      // print the string buffer after appending
      System.out.println("After append = " + buff);
      buff = new StringBuffer("abcd ");
      System.out.println("buffer = " + buff);

      // appends the boolean argument as string to the string buffer
      buff.append(false);

      // print the string buffer after appending
      System.out.println("After append = " + buff);
   }
}

Output

buffer = tuts
After append = tuts true
buffer = abcd
After append = abcd false
