java取两个字符串的最大交集

本文实例讲述了java取两个字符串的最大交集的实现方法，分享给大家供大家参考。具体实现方法如下：

package com.itheima.net;

public class Game13

{

    public static void main(String[] args)

    {

        String s1 = "135adbfg67";

        String s2 = "125dbf59";

        String s3 = s2;

        int begin = 0;

        int end = s2.length();

        int i = 1;

        while (!s1.contains(s3))

        {

            if (end == s2.length())

            {

                begin = 0;

                end = (s2.length()) - (i++);

            }

            else

            {

                begin++;end++;

            }

            s3 = s2.substring(begin, end);

            System.out.println(s3);

            System.out.println("--------");

        }

        System.out.println(s3);

    }

}

package com.itheima.net;

public class Game15

{

    public static void main(String[] args)

    {

        String s1 = "135adbfg67";

        String s2 = "125dbf59";

        method(s2, s1);

    }

    public static void method(String max, String min)

    {

        if (max.length() < min.length())

        {

            String s = max;

            max = min;

            min = s;

        }

        String subStr = min;

        for (int begin = 0, end = min.length(), i = 1; !max.contains(subStr); subStr = min.substring(begin, end))

        {

            if (end == min.length())

            {

                begin = 0;

                end = (min.length()) - (i++);

            }

            else

            {

                begin++;

                end++;

            }

            System.out.println(subStr);

            System.out.println("--------");

        }

        System.out.println(subStr);

    }

}
