代码如下：
import java.lang.StringBuffer.*;

public class ContinueExample
{
    public static void main(String args[])
    {
        StringBuffer searchMe = new StringBuffer("Peter Piper picked a peck of picked peppers");
        int max = searchMe.length();
        int numps = 0;
        for (int i = 0;i < max ;i++)
        {
            if(searchMe.charAt(i) != 'p')
            {
                continue;
            }
            numps++;
            searchMe.setcharAt(i,'P');
        }
        System.out.println("Found"+numps+"p's in the old string .");
        System.out.println("The new string is :");
        System.out.println(searchMe);
    }
}
可是编译时出现如下错误：
ContinueExample.java:24: 找不到符号
符号： 方法 setcharAt(int,char)
位置： 类 java.lang.StringBuffer
                        searchMe.setcharAt(i,'P');
各位大哥，谢啦！！！
