Creation of String Buffer

In this section, you will learn how to create a string buffer. Here we have used the following StringBuffer Constructors.

StringBuffer() //Default Constructor with 16 characters set
StringBuffer(String s) //String to String Buffer
StringBuffer(int initialCapacity) //StringBuffer?s with initial Capacity

Description of code:

As mentioned above we have taken three String buffer constructors here. One is the default with 16 characters and other two takes the String buffer and capacity of StringBuffer. Therefore we get the following output.

public class StringBufferExample{   public static void main(String[] args) {   StringBuffer strBuffer1 = new StringBuffer("Bonjour");     StringBuffer strBuffer2 = new StringBuffer(60);     StringBuffer strBuffer3 = new StringBuffer();        System.out.println("strBuffer1 : " +strBuffer1);   System.out.println("strBuffer2 capacity : " +strBuffer2.capacity());   System.out.println("strBuffer3 capacity : " +strBuffer3.capacity());   } }

Output of the program:

C:\unique>javac StringBufferExample.java C:\unique>java StringBufferExample strBuffer1 : Bonjour strBuffer2 capacity : 60 strBuffer3 capacity : 16 C:\unique>
