class asdf {
	private String str;
	public String getStr(){
		return str;
	}
	public void serStr(String str){
		this.str=str;
	}
	public String reverse(String s){
		int len=s.length();
		StringBuffer buffer=new StringBuffer(len);
		for(int i=len-1;i>=0;i--)
			buffer.append(s.charAt(i));
		return buffer.toString();
	}
}
public class asd{
	public static void main(String args[]){
		asdf a=new asdf();
		a.serStr("这是一个字符串--This is a test string");
		System.out.println("正常字符串："+a.getStr());
		System.out.println("翻转字符串："+a.reverse(a.getStr()));
	}
}
