字符串反转

写出一个程序，接受一个字符串，然后输出该字符串反转后的字符串。（字符串长度不超过1000）

package nowcoder;

public class ReverseStringSolution {
    public String solve(String str){
        String reverse = "";
        int length = str.length();
        for(int i=0 ; i < length;i++){
            reverse = str.charAt(i) + reverse;
        }
        return reverse;
    }
    public static void main(String[] args){
        String target ="abcdef";
        String reverse = new ReverseStringSolution().solve(target);
        System.out.println(reverse);
    }
}
