Here is a code that accepts 10 strings from the string and stored into array and then find the string with the maximum length.

import java.util.*;

class StringExample{
public static String compare(String st1, String st2){
if(st1.length()>st2.length()){
return st1;
}
else{
return st2;
}
}
public static void main(String []args){
String word = "";
Scanner input=new Scanner(System.in);
String stringArray[] = new String[10];
System.out.println("Enter strings: ");
for(int i=0;i<stringArray.length;i++){
stringArray[i]=input.nextLine();
}
for(int i=0;i<stringArray.length;i++){
if(i==0){
word = stringArray[0];
}
word = compare(word, stringArray[i]);
}
System.out.println("Longest word = " + word);
}
}
