Java:stringbuffer Character processing objects

1. Adding characters

public class Stringbufferdemo {public static void main (String args[]) {StringBuffer SBF = new StringBuffer (); Sbf.append ("H Ello World "), Fun (SBF), for (int i =0; i <; i++) {sbf.append (i);} System.out.println (SBF);} public static void Fun (StringBuffer b) {b.append (""). Append ("\ r \ n");}

　　

2, append character

public class StringBufferDemo2 {public static void main (String args[]) {StringBuffer SBF = new StringBuffer (); Sbf.append (" Hello World "); Sbf.insert (1,"-gaga-"); Sbf.insert (0,"/wiki/"); System.out.println (SBF);}}

　　

3, deleting characters

public class StringBufferDemo3 {public static void main (String args[]) {StringBuffer SBF = new StringBuffer (); Sbf.append (" Omganggangstyle "); Sbf.delete (0, 10); System.out.println (SBF);}}

　　

4. Character reversal

public class StringBufferDem4 {public static void main (String args[]) {StringBuffer SBF = new StringBuffer (); Sbf.append ("H Ello World "); System.out.println (Sbf.reverse ());}}
