获取两个字符串包含最大的字串

public class StringTest2 {

 public static String getMaxSubString(String s1,String s2){

String max="",min="";

max=(s1.length()>s2.length())?s1:s2;

min=(max==s1)?s2:s1;


for(int x=0;x<min.length();x++){

for(int y=0,z=min.length()-x;z!=min.length()+1;y++,z++){

String temp=min.substring(y,z);

if(max.contains(temp)){

System.out.println(temp);

return temp;

}


}

}

return "";

 }



 public static void main(String[] args) {

String s1="sdsdshelloddfgh";

String s2="hello";

getMaxSubString(s2,s1);

 }

 }
