In the below example, it inserts the new string at position 4 hence prints the output as “Javalanguage”.Start Your Free Software Development Course We can use the insert() method to insert a new string at the required index position. Example: insert() method – Java StringBuffer class Let’s see various examples by using different StringBuffer methods.

The capacity is 16 plus the length of the string argument StringBuffer methods in Javaīelow are the StringBuffer methods Methods Description StringBuffer append(String s) Appends the specified string to the original string StringBuffer append(CharSequence csq, int start, int end) Appends the specified portion of the character sequence to the original string int capacity() Returns the current capacity of the StringBuffer char charAt(int index) Returns the character at the specified index position int codePointAt(int index) Returns the codepoint character at the specified index StringBuffer delete(int start, int end) Deletes the characters from the StringBuffer starting form the specified start index to end index StringBuffer deleteCharAt(int index) Deletes the character at the specified index void ensureCapacity(int capacity) Ensures that the StringBuffer has the minimum specified capacity int indexOf(String str) Returns the index of the specified substring present in the string StringBuffer insert(int offset, String str) Inserts the specified string at the specified index int lastIndexOf(String str) Returns the index of the last occurrence of the specified substring int length() Returns the number of characters of the string StringBuffer replace(int start, int end, String str) Replaces the substring with the specified string starting from the start index till the end index StringBuffer reverse() Reverses the characters in the specified string void setCharAt(int index, char ch) Sets the specified character at the specified index in the input string void setLength(int newLength) Sets the new length of the character string String subString(int start, int end) Returns a substring of the string starting from the specified start index to end index String toString() Returns the string representation of the StringBuffer object void trimToResize() Trims the storage size of the CharacterSequence StringBuffer examples The capacity is 16 plus the length of the characters in the argument StringBuffer(int initialCapacity) Creates an empty StringBuffer with the specified capacity StringBuffer(String str) Creates a StringBuffer with the specified string. The StringBuffer class contains the below constructors: Constructor Description StringBuffer() Creates an empty default constructor with initial capacity as 16 StringBuffer(CharSequence csq) Creates a StringBuffer with the characters in the specified CharSequence. Inherits all the methods from the Object class.
Implements the CharSequence, Appendable, and Serializable interfaces.It is thread-safe and synchronized which means we can use it for multithreading.
We will also see the difference between StringBuffer vs StringBuilder towards the end of the tutorial.īelow are the features of the StringBuffer class: In this tutorial, we will discuss the StringBuffer class in Java and methods in detail with examples. Strings are immutable which means it is of fixed length whereas StringBuffer is mutable and growable meaning we can change the length of string and do different manipulations like append, delete, insert, etc. The StringBuffer in Java is a class that we can use to manipulate Strings. StringBuffer vs StringBuilder StringBuffer class in Java.Example: Other methods of Java StringBuffer.Example: capacity() method – StringBuffer.Example: reverse() method – StringBuffer.Example: delete() and deleteCharAt() method.
