判断A字符串是B字符串的反转

Posted 2020-10-13 JohnKing

先将其中一个字符串进行反转操作,然后两个字符串进行判断.

1.反转

    /**
     * 字符串反转
     * @param str
     * @return
     */
    private static String convert(String str){        
        char[] charArray = str.toCharArray();
        int len = charArray.length;
        char[] des = new char[len];
        for(int i = 0; i < len; i++){
            des[len - i -1] = charArray[i];
        }        
        return String.valueOf(des);
    }

2.判断

    /**
     * 判断两个字符串是否互为反转字符串
     * @param a
     * @param b
     * @return
     */
    private static boolean isReverse(String a,String b){
        String str = convert(a);
        return b.equals(str);
    }

3.测试

    public static void main(String[] args){        

        String a = "abcdef";
        String b = "fedcba";
        String c = "abcdfe";
        System.out.println(isReverse(a,b));//true
        System.out.println(isReverse(a,c));//false        
    }
