java例程练习（StringBuffer类） - JAVA

public class TestBuffer {//StringBuffer存储变长的字符序列，String类是不可变长的字符序列
public static void main(String[] args) {
String s = "Mircosoft";
char [] c = {'a', 'b', 'c'};
StringBuffer sb1 = new StringBuffer(s);
sb1.append('/').append("IBM").append('/').append("Sun");
System.out.println(sb1);

StringBuffer sb2 = new StringBuffer("数字");
for(int i = 0; i < 9; i++) {
sb2.append(i);
}

System.out.println(sb2);

sb2.delete(8, sb2.length()).insert(0, c);
System.out.println(sb2);
System.out.println(sb2.reverse());
}
}
