Java中的StringBuffer
/**
*
*/
package com.you.model;
/**
* @author YouHaidong
*
*/
public class StrFoo
{
/**
* @param args
*/
public static void main(String[] args)
{
StringBuffer a = new StringBuffer("A");
StringBuffer b = new StringBuffer("B");
operate(a, b);
System.out.println(a + "," + b);
}
/**
*
* @param x
* @param y
*/
public static void operate(StringBuffer x,StringBuffer y)
{
x.append(y);
y = x;
}
}
运行结果：
AB,B
