public class Main {//NowJava.com - 时代Java 提 供

public static void main(String[] args) {

//StringBuffer append(boolean b) method

boolean b = true;

StringBuffer sb1 =  new StringBuffer("BooelanAppended : ");

sb1.append(b);

System.out.println(sb1);

//StringBuffer append(char c) method

char c = 'Y';

StringBuffer sb2 =  new StringBuffer("CharAppended : ");

sb2.append(c);

System.out.println(sb2);

/*StringBuffer append(char[] c) method

to StringBuffer object*/

char[] c1 = new char[] {'Y','e','s'};

StringBuffer sb3 =  new StringBuffer("Character Array Appended : ");

sb3.append(c1);

System.out.println(sb3);/**来 自 N  o w  J a v a . c o m**/

//StringBuffer append(double d) method

double d = 1.0;

StringBuffer sb4 =  new StringBuffer("doubleAppended : ");

sb4.append(d);

System.out.println(sb4);

//StringBuffer append(float f) method

float f = 1.0f;

StringBuffer sb5 =  new StringBuffer("floatAppended : ");

sb5.append(f);

System.out.println(sb5);

//StringBuffer append(int i) method

int i = 1;

StringBuffer sb6 =  new StringBuffer("integerAppended : ");

sb6.append(i);

System.out.println(sb6);

//StringBuffer append(long l) method

long l = 1;

StringBuffer sb7 =  new StringBuffer("longAppended : ");

sb7.append(l);

System.out.println(sb7);

//StringBuffer append(Object o) method

/* NOTE : Objects are first converted to a String and then it is

appended to StrinBuffer */

Object obj = new String("Yes");
