java 两个长度不同的字符串交叉混合

[weixin_44667356]

比如 “Halifax” 和 “Dartmouth”， 混合完变成 “HDaalritfmaoxuth”， 应当如何编码？

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String str1 = "1234";
		String str2 = "asdfghj";
		
		String result = "";
		
		int i = -1;
		while(i++ < str1.length() - 1 || i < str2.length())
			result += (i < str1.length() ? str1.charAt(i) + "" : "") + (i < str2.length() ? str2.charAt(i) : "");
			
		System.out.println(result);
	}

            cs[2 * i] = a.charAt(i);
            cs[2 * i + 1] = b.charAt(i);
        }
        if (a.length() == max)
            a.getChars(min, max - 1, cs, min * 2);
        if (b.length() == max)
            b.getChars(min, max, cs, min * 2);
        return new String(cs);
    }
}

上面有点小问题，这个是对的

public class Test2
{
    public static void main(String[] args) {
        String a = "Halifax";
        String b = "Dartmouth";
        System.out.println(main(a, b));
    }

    public static String main(String a, String b) {
        char[] cs = new char[a.length() + b.length()];
        int min = Math.min(a.length(), b.length());
        int max = Math.max(a.length(), b.length());
        for (int i = 0; i < min; i++)
        {
            cs[2 * i] = a.charAt(i);
            cs[2 * i + 1] = b.charAt(i);
        }
        if (a.length() == max)
            a.getChars(min, max - 1, cs, min * 2);
        if (b.length() == max)
            b.getChars(min, max, cs, min * 2);
        return new String(cs);
    }
}

额 怎么没法删回帖

public class Test2
{
    public static void main(String[] args) {
        String a = "Halifax";
        String b = "Dartmouth";
        System.out.println(main(a, b));
        System.out.println(main(b, a));
    }

    public static String main(String a, String b) {
        char[] cs = new char[a.length() + b.length()];
        int min = Math.min(a.length(), b.length());
        int max = Math.max(a.length(), b.length());
        for (int i = 0; i < min; i++)
        {
            cs[2 * i] = a.charAt(i);
            cs[2 * i + 1] = b.charAt(i);
        }
        if (a.length() == max)
            a.getChars(min, max, cs, min * 2);
        if (b.length() == max)
            b.getChars(min, max, cs, min * 2);
        return new String(cs);
    }
}
