The given code finds the longest word from the string.

import java.util.*;

return st1;
}
else{

}
}

String word = "";
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);
}
public static void main(String []args){
new LongestWord();
}
}
