Detailed explanation of how to find the maximum intersection of two strings in Java

This article mainly introduces the method of java to get the maximum intersection of two strings. It involves Java's string manipulation skills and has certain reference value. Friends who need it can refer to it

The example in this article describes the implementation method of obtaining the maximum intersection of two strings in Java, and shares it with you for your reference. The specific implementation method is as follows:

The code is as follows:

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);
    }
}

The code is as follows:

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);
    }
}
