Java语言字符串判断是否是回文数的程序，回文数就是颠倒以后和自身相同的

Answer 1

private boolean judgeHW(char[] abc) {
        char[] a, b;
        int l = abc.length;
        if (l % 2 == 0) {
            a = new char[l / 2];
            b = new char[l / 2];
            System.arraycopy(abc, 0, a, 0, a.length);
            System.arraycopy(abc, a.length, b, 0, b.length);
        } else {
            int m = (l - 1) / 2;
            a = new char[m];
            b = new char[m];
            System.arraycopy(abc, 0, a, 0, a.length);
            System.arraycopy(abc, m+1, b, 0, b.length);
        }
        return judgeHW(a, b);
    }

    private boolean judgeHW(char[] a, char[] b) {
        boolean c = true;
        for (int i = 0; i < a.length; i++) {
            c &= a[i] == b[b.length - i - 1];
        }
        return c;
    }
