It returns the resulting StringBuffer object.These methods are shown here: The deleteCharAt( ) method deletes the character at the index specified by loc. The resulting StringBuffer object is returned. Thus, the substring deleted runs from start Index to endIndex–1. Here, start Index specifies the index of the first character to remove, and end Index specifies an index one past the last character to remove. (s) // returns iA.roturPĭelete( ) and deleteCharAt( ): It can delete characters within a StringBuffer by using the methods delete( ) and deleteCharAt( ).The delete( ) method deletes a sequence of characters from the invoking object. StringBuffer s = new StringBuffer("Prutor.Ai") Here, index specifies the index at which point the string will be inserted into the invoking StringBuffer object. StringBuffer insert(int index, String str) Insert( ): It is used to insert text at the specified index position. StringBuffer s = new StringBuffer("prutordot") ("Capacity of string PrutordotAi=" + q) Īppend( ): It is used to add text at the end of the existence text. StringBuffer s = new StringBuffer("PrutordotAi") Length( ) and capacity( ): The length of a StringBuffer can be found by the length( ) method, while the total allocated capacity can be found by the capacity( ) method. StringBuffer s=new StringBuffer("PrutordotAi") StringBuffer(String str): It accepts a String argument that sets the initial contents of the StringBuffer object and reserves room for 16 more characters without reallocation. StringBuffer( int size)It accepts an integer argument that explicitly sets the size of the buffer. StringBuffer( ): It reserves room for 16 characters without reallocation. It will automatically grow to make room for such additions and often has more characters preallocated than are actually needed, to allow room for growth. StringBuffer may have characters and substrings inserted in the middle or appended to the end. String represents fixed-length, immutable character sequences while StringBuffer represents growable and writable character sequences. StringBuffer is a peer class of String that provides much of the functionality of strings.
