public class MyDemo2 {

String str = ".ymene tsrow sih si nam yrevE";
StringBuffer sb = new StringBuffer(str);
System.out.println(str+"反转"+sb.reverse());
}
}
import java.io.BufferedReader;
public class PatternDemo01{
public static void main(String args[]){
StringBuffer buf = new StringBuffer() ;
buf.append(".ymene tsrow sih si nam yrevE") ;
String str = buf.reverse().toString() ;
System.out.println(str);
}
}
直接用StringBuffer中的reverse()进行反转操作
